El investigador Stevenson de CIAS dijo que en un comienzo funciona mejor para las personas que utilizan cifras pequeñas, alrededor […]

La mayoría de los pollos parrilleros (también conocidos como pollos de engorde o ‘broilers’ en inglés), ponedoras, y otras aves domesticadas fueron criadas al exterior antes de la introducción a finales de los años 50 del ahora dominante método en confinamiento. Desde […]

Mohler Ideally, weed management in an organic cropping system involves the integration of a broad range of cultural practices. Although cultivation after planting is usually a key component, a variety of other factors make important contributions to weed control on organic farms (table 3.6). All of these practices occur within the context […]

Stoner The effectiveness of crop rotation as a tool for insect management depends on the life cycle of the target insect. For crop rotation to control an insect pest well, the insect must spend the period from the end of one crop to the beginning of the next in a stage with […]

To successfully use crop rotation for disease management, however, requires understanding the life cycle of the disease-causing organism (pathogen). Generally, the technique of using crop rotation for disease management is to grow non-host […]

These reservoirs, however, are not all available to the crop. In an organic crop rotation, the grower manages soil organic matter and nutrient availability by incorporating different crop residues, cycling among crops with different nutrient needs, using cover crops, and […]

Favorable tilth implies good conditions for seed germination and root proliferation, allowing crops to thrive. Also, a soil with good tilth facilitates other processes, such as water infiltration and aeration, which benefit both crop and […]

Mohler This chapter is about the ways biologists and soil scientists view crop rotation. Unlike the farmer experts of the previous chapter, who approach rotation as a holistic process, the scientists are specialists who delve deeply into particular aspects of organic production. They study in detail how crop rotation affects a particular […]
