Good management of field residues can increase efficiency of irrigation and control of erosion. The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced-till agriculture practices are carried out to maximize crop residue cover. Simple line-transect measurements can be used to estimate ...
The absence of environmentally friendly agricultural waste management further leads to animal suffering, water pollution, fertilisation, and decline in biodiversity, among others. [ 25 ] According to the waste hierarchy , burning agricultural waste for the sake of energy generation is a less environmentally friendly treatment method than ...
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required for continuous confined animal operations ...
No-till farming is used in the United States and the area managed in this way continues to grow. This growth is supported by a decrease in costs. No-till management results in fewer passes with equipment, and the crop residue prevents evaporation of rainfall and increases water infiltration into the soil. [17]
Different types of tillage result in varying amounts of crop residue being incorporated into the soil profile. Conventional or intensive tillage typically leaves less than 15% of crop residues on a field, reduced tillage leaves 15–30%, and conservation tillage systems leave at least 30% on the soil surface. [10]
At least 30% of plant residue remains on the soil surface in conservation tillage. [19] [20] Reduced-tillage or no-till operations limit the amount of soil disturbance while cultivating a new crop, and help to maintain plant residues on the surface of the soil for erosion protection and water retention.
Increasing the angle of disks causes residues to be buried more deeply. Increasing their concavity makes them more aggressive. Chisel plows can have spikes or sweeps. Spikes are more aggressive. Percentage residue is used to compare tillage systems because the amount of crop residue affects the soil loss due to erosion. [22] [24]
Although originally developed for agricultural pest management, [17] IPM programmes now encompass diseases, weeds and other pests that interfere with management objectives for sites such as residential and commercial structures, lawn and turf areas, and home and community gardens. Predictive models have proved to be suitable tools supporting ...
