The diagram below shows fertilizer consumption by the European Union (EU) countries as kilograms per hectare (pounds per acre). The total consumption of fertilizer in the EU is 15.9 million tons for 105 million hectare arable land area [51] (or 107 million hectare arable land according to another estimate [52]). This figure equates to 151 kg of ...
In agriculture, the yield is a measurement of the amount of a crop grown, or product such as wool, meat or milk produced, per unit area of land. The seed ratio is another way of calculating yields. Innovations, such as the use of fertilizer, the creation of better farming tools, new methods of farming and improved crop varieties, have improved ...
Food production per capita since 1961 Grain silos Rice plantation in Thailand Cambodians planting rice, 2004. Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural ...
Therefore, pure KCl is 39.09/(39.09 + 35.45) = 52% potassium and 48% chlorine by weight. Its K value is therefore 52/0.83 = 63; that is, a fertilizer that gets all its potassium from K 2 O and has the same potassium contents as pure KCl would have to be 63% K 2 O. Pure KCl fertilizer would thus be labeled 0-0-63.
A 2000 assessment of agriculture in the UK determined total external costs for 1996 of £2,343 million, or £208 per hectare. [200] A 2005 analysis of these costs in the US concluded that cropland imposes approximately $5 to $16 billion ($30 to $96 per hectare), while livestock production imposes $714 million. [201]
Stocking is a quantitative measure of the area occupied by trees, usually measured in terms of well-spaced trees or basal area per hectare, relative to an optimum or desired level of density. [1] It is also used as a measure of the growth potential of a site that may be affected by vegetation in the area along with other nearby trees.
The annual average fertiliser requirement in Nepal to replenish the soil nutrition is 310 kg per hectare but only 29 kg of fertiliser is added to the soil. [1] Fifty per cent of nutrient loss from the soil occurs during the early monsoon. [2] The use of fertiliser is relatively new to Nepal.
150–200 kg N per hectare; 80–120 kg P 2 O 5 per hectare; 180–250 kg K 2 O per hectare; 110–150 kg Ca per hectare; 20–40 kg Mg per hectare; Fertilizer recommendations are in the range of the nutrient removal. [14] [28] [30] Organic fertilizer must be applied before sowing due to the short cultivation time of napa cabbage and the slow ...
