2021-12-1 · Soil phosphorus mining will come at a cost for the farmer. Abstract. Soil phosphorus (P) leaching is one of the major causes of diffuse P losses towards the environment in north-west Europe. In order to cut back these P losses over the long term, soil P stocks need to be drastically reduced. Greenhouse experiments have shown that a rapid ...
Read More2020-5-20 · This study evaluated the utility of the “soil phosphorus storage capacity” (SPSC) as an indicator of safe P mining for acid soils. The SPSC predicts crop-available legacy P in absolute terms, (i.e., kg ha −1 ; can be calculated from mg kg −1 if the bulk density and soil depth are known), which is not provided by current soil tests.

Because this reduces the amount of soil phosphorus available, humans started adding phosphorus fertilizer to soils in the 1800s. Some of the fertilizer was organic, from ground up bones or mined guano (bat dung). But humans then started mining phosphorus

Read More2020-5-6 · Soil phosphorus (P) is a major driver of forest development and a critically limited nutrient in tropical soils, especially when topsoil is removed by mining. This nutrient can be present in soils in the form of different fractions, which have direct consequences for P availability to plants and, consequently, for restoration success.

China — The country’s phosphate mining production decreased in 2018 to 140 million metric tons (MT) from 144 million MT in 2017, which is likely a result of Beijing’s environmental crackdown on the mining industry. There has also been speculation in the past that China’s phosphate production in 2017 may have been overstated.

Read More2015-3-11 · Phosphorus fertilizer rates have, pretty generally, lagged crop removal for some time. As crops remove the soluble phosphorus in the soil, the soil’s large reserve of less soluble forms will transfer some more phosphorus into the available “labile” pool. However, this labile pool may be losing its ability to keep up, resulting in a “hidden hunger” for phosphate in many crops in ...
