All plants, including crop, require air (specifically, oxygen) to respire, produce energy, and keep their cells alive. In agriculture, waterlogging typically blocks air from getting to the roots. [3] With the exception of rice (Oryza sativa), [4] [5] most crops like maize and potato, [6] [7] [8] are therefore
Water is a particularly important issue in dryland farming. The ability to collect and store water at a low cost and without damaging the environment, is what opens up deserts and other arid regions to farmers. When it rains in dryland areas, the rain storms are normally heavy, and the soil unable to absorb the large amounts of rain that comes ...
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
Aside from occasional weeding and mulching, xeriscaping requires far less time and effort to maintain. [16] This is the case because under xeriscaping principles the vegetation used for urban greenspaces are indigenous to the area; therefore, are less expensive and require less assistance to acclimate and survive in the environment when ...
In addition to reducing water loss at the sink, more sustainable ways to harvest water also can be used. Many modern small (nonindustrial) farmers are using rain barrels to collect the water needed for their crops and livestock. On average, rainwater harvesting where rain is frequent reduces the cost of water in half. [23]
The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others.
Crop coefficients, as used in many hydrological models, usually change over the year because crops are seasonal and, in general, plant behaviour varies over the year: perennial plants mature over multiple seasons, while annuals do not survive more than a few [clarification needed], so stress responses can significantly depend upon many aspects ...
Rainfed agriculture is a type of farming that relies on rainfall for water. It provides much of the food consumed by poor communities in developing countries.E.g., rainfed agriculture accounts for more than 95% of farmed land in sub-Saharan Africa, 90% in Latin America, 75% in the Near East and North Africa, 65% in East Asia, and 60% in South Asia.
