- Weed control in smallholder Conservation Agriculture(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.One of the principle reasons why farmers plough the soil is to control weeds. Tillage is easy and weed control can be complete. Weed control without tillage is more complicated and requires much more knowledge. A lot of farmers find controlling weeds in the first seasons of conversion from conventional agriculture to conservation agriculture (CA) to be very difficult. This can lead to a rejection of the technology.
Publication - Manual and animal traction seeding systems in Conservation Agriculture(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.Soil tillage leads to the breakdown of soil structure and land degradation (see bulletin on land and soil degradation) and is therefore not sustainable. However to be able to plant into unploughed soil, special methods or equipment are necessary. Both man
Publication - The importance of crop rotations(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.A crop rotation is a series of different crops planted in the same field following a defined order (i.e. maize-cotton-sunnhemp or maize-soyabeans). Monoculture is the repeated planting of the same crop in the same field year after year.
Publication - The role and importance of residues(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.Crop residues consist of dead plant parts, or stover, that remain from previous crops, including green manure cover crops, and may be supplemented with dried weeds or other imported plant material. Soil cover is one of the most critical factors in ensuring the success of conservation agriculture (CA). In conventional agricultural systems, residues are usually fed to animals, taken off the field for other uses, incorporated or burned. In many places communal grazing rights are observed, and protecting the residues on the fields from free roaming animals can entail considerable conflicts. However, farmers managing CA systems derive huge benefits from surface residue retention, which makes keeping them on the fields very worthwhile, and some communities have found ways to overcome the problems of communal grazing rights.
Publication - Conservation Agriculture – a sustainable system(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.Conservation agriculture (CA) is a crop management system based on three principles: a) minimum soil movement (no soil inversion by tillage) b) soil surface cover with crop residues and/or living plants and c) crop rotations to avoid pest and diseases.
Publication - The problem of soil and land degradation(CIMMYT, 2015-04-21) Thierfelder, C.; Wall, P.C.Soil degradation has two major components: the loss of soil through erosion and the loss of soil fertility. Both components lead to progressively lower crop yields, increased costs of production, and may end up in land abandonment and desertification. Soil tillage is the principle cause of degradation of cropped fields. Soil tillage causes rapid breakdown of soil organic matter - the key to soil fertility.
