Secure yields – even under extreme conditions.

Erosion protection through soil structure

Water infiltrates instead of running off

Erosion is one of the greatest threats to agricultural soils. Every year, thousands of tons of fertile topsoil are lost in Germany due to water and wind erosion. Erosion destroys soil structures, reduces fertility, and silt up waterways.

Causes of water erosion:

Water erosion occurs when water runs off the surface, carrying soil material with it. The main cause: compacted soils that do not absorb water well. During heavy rainfall, rivulets form and deepen into erosion channels.

How DUTZI machines prevent erosion:

Non-destructive deep-acting loosening with the DUTZI front subsoiler creates vertical drainage channels. The hairline cracks act as infiltration points: water quickly penetrates deep into the soil instead of running off the surface. This reduces surface runoff by 60–80% (depending on soil conditions).

Surface protection through crop residues:

The DUTZI KR works crop residues into the soil at a shallow depth (5–8 cm). Some of the residues remain on the surface as a protective mulch layer. This layer cushions raindrops, prevents silting, and retains moisture in the soil.

Preventing silting:

Silting occurs when raindrops smash the soil surface and release fine soil. This fine soil clogs soil pores – infiltration is blocked and surface runoff increases.

Prevent wind erosion:

Wind erosion occurs on open, dry areas – especially in spring after plowing. DUTZI systems work without plowing, leaving crop residues on the surface and creating roughness. This slows down the wind, preventing wind erosion and soil drift.

Long-term erosion resistance:

Soils that have been worked with DUTZI for years develop more stable structures: humus increases, soil aggregates become more stable, and roots interweave the soil. These soils are more resistant to erosion – even in extreme conditions.

Conclusion:

Erosion protection begins with good soil structure. DUTZI machines create this structure mechanically – through deep loosening, controlled crumbling, and shallow incorporation. The result: water penetrates, soil remains in place, and fertility is preserved.

Drought resilience through deep roots

Using water from deep underground

Drought is the greatest challenge for agriculture in Central Europe. Periods of drought are becoming longer, heat waves more frequent, and rainfall more unpredictable. Plants that survive drought need deep roots.

Long-term drought resilience:

Farms that have been working with DUTZI for years report more stable yields in dry years. The soil structure is better, humus increases (storing water), and roots penetrate deeper. These soils are better at buffering drought.

Climate scenarios:

Climate models predict more frequent droughts for Central Europe. Farms that invest in soil health now are better prepared. Deep loosening is a strategy for adapting to climate change – mechanically, without additional costs.

Conclusion:

Drought resilience starts with deep roots. Deep roots need open soils. DUTZI machines create this openness – through deep loosening, hairline cracking, and sustainable soil structure. The result: plants that survive drought because they can use water from deep down.

Managing heavy rainfall events

Drain water quickly, prevent damage

Heavy rainfall is on the rise – events with 50–100 mm of precipitation in just a few hours are no longer a rarity. Such large amounts of water overwhelm compacted soils: water accumulates, flows off the surface, causing erosion, silting, and waterlogging.

The problem with compacted soils:

Compacted soils absorb water slowly – often only 5–10 mm/h. During heavy rainfall of 50 mm/h, 40–45 mm flows off the surface. The result: puddles, erosion channels, flooding, silted-up water bodies.

DUTZI loosening increases the infiltration rate:

Deep loosening with the DUTZI front subsoiler increases the infiltration rate by a factor of 3–5. Loosened soils absorb 20–40 mm/h (depending on soil type). This significantly reduces surface runoff.

Practical example of heavy rainfall:

A corn farm experienced a heavy rainfall event (80 mm in 2 hours). Water covered the entire field. The farmer carefully drove the front subsoiler into the wet soil to open it up.

Result:

• Within 3 days, the water had seeped away.
• The corn recovered completely.
• No erosion damage, no puddles
• During the subsequent dry phase, the corn used the water that had seeped away from deep underground

Avoiding waterlogging:

Waterlogging occurs when water stands above a compacted layer and cannot seep away. Plants suffocate, roots rot, yields collapse. Non-destructive deep-acting loosening breaks through the compaction. Water is absorbed by the soil, oxygen can flow in, roots can grow. Waterlogging is prevented.

Drainage effect:

The hairline cracks created by DUTZI loosening act as natural drainage. They quickly drain water into deeper layers – without the need for technical drainage. And the water remains available to the roots.

Rule of thumb: 1 ha of DUTZI-loosened soil can absorb 100–200 m³ of additional water during heavy rainfall (depending on soil type and loosening depth).

Erosion protection during heavy rainfall:

Rapid infiltration prevents surface runoff. No runoff = no erosion. Areas treated with DUTZI show intact surfaces even after heavy rainfall – no soil erosion, no gullies, no silting.

Climate scenarios:

Climate models predict more frequent heavy rainfall events. Farms that are prepared for heavy rainfall avoid damage, crop losses, and soil loss. Non-destructive deep-acting loosening is a preventive measure.

Conclusion:

Heavy rainfall is becoming the norm. Soils must be able to absorb water quickly – otherwise there is a risk of erosion, waterlogging, and crop failures. DUTZI machines create the conditions for rapid infiltration: deep loosening, hairline cracks, open soil structures. The result: water penetrates, damage is avoided, and soils remain intact.

Stable yields through soil health

Healthy soils = stable yields

Yield stability is more important than peak yields. A farm that harvests 8 t/ha of wheat in 8 out of 10 years is more economically successful than a farm that harvests 10 t/ha in 5 years but only 4 t/ha in the other 5 years (due to drought, waterlogging, erosion).

What stabilizes yields?

• Deep roots: access water and nutrients from deeper layers, buffer drought stress
• Active soil life: mobilizes nutrients, builds humus, stabilizes soil structure
• Good soil structure: enables rapid infiltration, prevents waterlogging, resists erosion
• Humus formation: stores water, binds nutrients, improves soil physics

DUTZI machines create these conditions:

• Non-destructive deep-acting loosening: creates root space, opens up soil for water and air
• Crumbling: creates stable soil aggregates, promotes soil life
• Incorporation of crop residues: provides organic material for humus formation
• Soil conservation: reduces passes, prevents renewed compaction

Long-term yield development:

Studies show that farms that have been working with DUTZI for 10+ years have more stable yields – especially in extreme years (drought, heavy rainfall). Yield volatility decreases by 15–25% (depending on farm structure).

Practical example of a long-term comparison:

One farm documented wheat yields over 15 years:

Before switching to DUTZI (years 1–5):

• Average yield: 7.2 t/ha
• Volatility: 4.8–9.5 t/ha (range: 4.7 t/ha)
• Extreme years: 3 years with yield losses >20%

After switching to DUTZI (years 6–15):

• Average yield: 7.8 t/ha (+8%)
• Volatility: 6.5–8.9 t/ha (range: 2.4 t/ha)
• Extreme years: 1 year with yield loss >15%

Conclusion: Higher average yields, significantly lower volatility, fewer extreme years.

Economic significance:

Yield stability means planning security. Farms can count on stable yields, plan liquidity, and make investments. Volatile yields make planning difficult, increase risk, and strain liquidity.

Rule of thumb: 10% less volatility = 5% greater economic stability (through better planning, less risk, more stable prices).

Humus formation as a long-term strategy:

DUTZI systems promote humus formation through:

• Shallow incorporation of crop residues (optimal decomposition depth)
• Activating soil life (more microorganisms = more humus formation)
• Soil conservation (fewer passes = less humus degradation)

Farms report 0.1–0.3% humus formation per year (depending on the initial level and cultivation). That may not sound like much, but it is significant: 0.2% humus = 2,000 kg C/ha = approx. 7,300 kg CO₂/ha bound.

Climate resilience:

Humus-rich soils buffer climate extremes better: they store more water (drought resilience), absorb water more quickly (heavy rainfall events), and resist erosion (structural stability).

Conclusion:

Yield stability is the result of healthy soils. Healthy soils are loose yet stable soils with active soil life and stable structures. DUTZI machines create these conditions – mechanically, sustainably, economically.

Long-term soil protection strategy

Regenerative tillage as a system

Soil protection is not a one-off event, but a continuous process. Regenerative tillage aims to improve soils in the long term – year after year, crop rotation after crop rotation.

Principles of regenerative tillage:

1. Avoid soil compaction: fewer passes, gentle machinery, no tillage when wet
2. Preserve soil structure: no-till cultivation, no turning, controlled crumbling
3. Promote soil life: Add organic material, aerate the soil, minimize chemical pollution
4. Prioritize soil protection: Prevent erosion, build up humus, manage water

DUTZI systems fulfill these principles:

• OnePass: reduces passes, protects soil structure
• Plowless: no turning, natural structures are preserved
• Non-destructive deep-acting loosening: opens soil to air and water, promotes soil life
• Shallow incorporation: crop residues at optimal decomposition depth, humus formation
• Durability: sustainable investment, no short-term compromises

Integration into operating system:

Regenerative soil cultivation works best when it is embedded in an overall system:

• Crop rotation: diversity increases soil health, cover crops protect the soil
• Fertilization: Organic fertilizers promote soil life, use mineral fertilizers sparingly
• Plant protection: minimize chemical use, consider mechanical alternatives
• Water management: Non-destructive deep-acting loosening, mulch layer, erosion protection

Long-term vision:

• Farms that have been working regeneratively for 10+ years report:
• Darker, humus-richer soils
• Higher earthworm populations
• More stable soil structures
• Lower fertilizer requirements (better nutrient availability)
• More stable yields

Economic sustainability:

Regenerative soil cultivation is economically sustainable:

• Lower operating costs (less diesel, less fertilizer, less plant protection)
• Higher yield stability (planning security)
• Long-term increase in value (healthier soils are more valuable)
• Subsidies (e.g., for humus formation, erosion control, climate protection)

Climate protection:

Regenerative soil cultivation contributes to climate protection:

• Humus formation binds CO₂ (0.1% humus = 3.7 t CO₂/ha)
• Less diesel = fewer CO₂ emissions
• Healthy soils emit less nitrous oxide (N₂O)

Conclusion:

Soil protection is securing the future. DUTZI machines are tools for this future – mechanical, sustainable, regenerative. Investing in soil health today means stable yields tomorrow.
