Comparison of No-Plough Cultivation, Mulch Sowing, and Strip-Till Cultivation

Three soil conservation technologies

No-plough cultivation, mulch sowing, and strip-till are farming methods aimed at minimizing soil disturbance, reducing costs, and saving work time. Below is a comparison of these methods.

No-Plough Cultivation

Definition: A cultivation system that eliminates traditional plowing. Sowing occurs directly in soil unprepared by previous plowing or harrowing.

Benefits: Reduces soil erosion, conserves moisture, decreases labor and fuel inputs, improves soil structure and biological activity.

Scope of Treatments: Limits mechanical disturbance of the soil structure to a minimum.

Mulch Sowing Technology

Definition: Sowing occurs in the presence of mulch, a layer of plant residues left on the soil surface.

Benefits: Protects soil from erosion, preserves moisture, inhibits weed growth, promotes biological activity in the soil.

Scope of Treatments: Emphasis on preserving plant remains on the soil surface. This can be combined with minimal tillage or no-tillage.

Strip-Till Cultivation

Definition: A cultivation method involving the preparation of narrow soil strips for sowing, while the remainder of the field remains unprocessed and covered with plant residues.

Benefits: Combines the advantages of conventional and no-plough cultivation - improved soil structure, moisture preservation, erosion reduction, and enhanced conditions for plant emergence in sowing areas.

Scope of Treatments: Preparation of narrow soil strips for sowing, with the remainder of the field left unprocessed.

In summary, no-till farming involves completely avoiding plowing and any deep tillage. Mulch seeding technology focuses on sowing in the presence of plant residues that remain on the soil surface, which may or may not be combined with no-till farming. Strip-till farming involves preparing narrow strips of soil for sowing while leaving the rest of the field undisturbed. The choice of the appropriate method depends on the individual needs of the farm, soil conditions, and the farmer's goals.

No-plough Cultivation

Soil cultivation is essential for maintaining its structure to achieve satisfactory crop yields and favorable economic returns. Among the numerous available tools and machines, select those that ensure the desired soil condition with the minimal number of passes in the field.

Plow sole problem

A common issue during plowing is the formation of a plow sole, an excessively compacted soil layer directly beneath the plowing depth. Hence, the plowing depth should be adjusted annually. Plowing large quantities of straw can create a straw layer at the furrow's bottom. Prior to adopting simplified tillage, the plow sole must be disrupted using a Rolmako subsoiler.

No-Plough Land Cultivation – Field Preparation

Prior to commencing no-plough cultivation, it is essential to regulate the water-air relations in the field. Subsoiling may often be necessary to remove the plow sole. Failure to undertake this task may result in water ponding. Utilization of the U624 chisel plow is recommended for soil preparation under the new tillage system. A common error observed in no-till cultivation, especially among newcomers, is conducting tillage operations excessively deep and frequently, particularly under conditions of high soil moisture. Such excessive activity leads to a gradual depletion of soil water, deteriorating plant growth conditions. Minimizing mechanical treatments to the essential minimum yields superior results. Weed control is best achieved with foliar herbicides since soil-applied herbicides may not be sufficiently effective in a no-plough system. When applying solid natural and organic fertilizers (manure, compost, etc.), it is crucial to distribute the fertilizer evenly across the field to prevent interference with tillage machinery operations. Optimal application times are in late autumn or early spring, and shallow mixing with the soil using a U693, U652, or SpeedCutter disc harrow is recommended. Prior to transitioning to a plowless system, regulating soil pH and maintaining its optimal level through liming every 2-4 years is advisable. No-till cultivation reduces evaporation, ensuring better rainwater absorption. Increased expenditure on weed control is necessary with no-plough sowing, thus effectively eliminating weeds immediately post-harvest is critical. Initially, stimulate weeds and self-seeding plants to germinate using the Rolmako SpringExpert mulch harrow, followed by destruction with a disc harrow or cultivator.

Machines for No-Till Cultivation

When transitioning to no-till cultivation, acquiring appropriate equipment is essential. No-till sowing is executed using a specialized seeder. Equipment for no-till cultivation typically includes components such as a no-till cultivator, e.g., Rolmako U436, Rolmako U652, or U671 disc harrow, and heavy Cambridge tillage rollers. It is advisable to consult with current users of such machinery to obtain direct feedback. This will help clarify your requirements and facilitate the selection of the appropriate device.

No-plough cultivation and environmental protection

No-plough cultivation minimizes soil disturbance, thus limiting water evaporation and retaining carbon in the ground. In a typical crop, carbon is brought to the surface and reacts with oxygen to turn into carbon dioxide. No-till farming reduces the emission of nitrous oxide (N2O), a greenhouse gas, by 40-70%. Moreover, it enriches biodiversity and benefits soil microorganisms. Even no-plough farming on a small farm is important for the environment.
