Sustainable land management technologies: minimum soil disturbance

Strip tillage is a cropping system for maize which reduces the reworking of the soil to the stripes, in which the seeds are planted. Strip tillage is a mixture between no tillage and conventional agriculture. Instead of ploughing and harrowing, a special rotary tiller including a grubber is used; it is used to avoid soil erosion or for economic reasons. The reworking of the soil, manuring, seeding and applying of herbicides can be done at once.

Maintenance of continuous soil cover; alternating crops and cover crops as a practice to improve soil quality and reduce diffuse agricultural water pollution. Continuous cover cropping has been promoted as an agro-environmental measure to extend sustainable land management and reduce diffuse water pollution. The type of crop species depends on the crop succession. Compared with systems that do not use cover crops, continuous soil cover provides long-term agronomical and environmental benefits due to a reduction of negative impacts on agro-ecosystems.

Leaving crop residues on the soil surface and subsequent planting through the mulch. The mulch layer has several important functions: it helps to increase and maintain water stored in the soil, reduces soil erosion, contributes to improve soil fertility and it efficiently controls weeds by hindering their growth and preventing weeds from producing seeds.
