The control and distribution of water by humans impacts water quality and quantity. Water conservation methods vary and help ensure adequate supplies for production and human use. Plant management affects quality and yields. Plant populations are related to yields per acre and quality of product. Harvesting techniques vary by crop, region and society.
Crop rotation affects soil tilth and fertility.
Pollination is essential to many fruit, nut and seed crops. Crop site selection is dependent upon several factors, including temperature, rainfall, microclimate, soil type and topography. Windbreaks have multiple purposes in crop production. Grazing systems are important plant management tools in livestock systems. Animal management is the application of scientific knowledge and technical skills to provide for animal health and productivity.
