Crop tolerance to seawater. Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water and seawater. There are crops that can grow on seawater and demonstration farms have shown the feasibility. [1] The government of the Netherlands reports a ...
Cattle eating silage. Silage is fodder made from green foliage crops which have been preserved by fermentation to the point of souring. It is fed to cattle, sheep and other ruminants. [1] The fermentation and storage process is called ensilage, ensiling, or silaging. The exact methods vary, depending on available technology, local tradition and ...
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
Livestock raising, and in particular cattle herding, is a major economic activity. Animal husbandry was the main source of livelihood for perhaps a third of Chad's people. The growing importance of cattle and meat exports underscored this point. In the 1960s and 1970s, these exports were estimated at between 25 and 30% of all merchandise exports.
Controlled-environment agriculture. Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming —is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...
The country exported NZ$ 46.4 billion worth of agricultural products (raw and manufactured) in the 12 months to June 2019, 79.6% of the country's total exported goods. [1] The agriculture, forestry and fisheries sector directly contributed $12.653 billion (or 5.1%) of the national GDP in the 12 months to September 2020, [2] and employed 143,000 ...
Cattle feeding. There are different systems of feeding cattle in animal husbandry. For pastured animals, grass is usually the forage that composes the majority of their diet. In turn, this grass-fed approach is known for producing meat with distinct flavor profiles. Cattle reared in feedlots are fed hay supplemented with grain, soy and other ...
