tested from various sources, they were found be soluble at a similar level to amorphous silica (i.e. not very soluble). “Theminimal half life time of larch and horsetail phytolithsin the interstitial soil solution ranges from 10–12 years at pH = 2–3 to < 1 year at pH above 6″....
But as soon as the phosphorus hit the soil, a large part of it reacted with soil minerals, forming substances that crops can’t access. Some also got locked away in equally unavailable organic forms. (Lawes生产的肥料含有一种植物很容易利用的磷。但一旦磷进入土壤,其中很大一部分就会与土壤矿...
Plants obtain water through their roots. Water present in the soil (or air, in the case of air plants) enters the plant through the epidermis of the root. The epidermis is a very thin single layer of cells. The water passes through the membranes of plant cells and also fills the spaces...
They have used quantitative methods, such as the cultural food significance index and use value to assess their importance within the region. The findings from these investigations hold significant implications, as they contribute not only to the preservation of the traditional knowledge of local wild...
Plants need phosphorus(磷) to grow. At first, people used organic or natural fertilizer. In1842 English agricultural chemist John Bennet Lawes patented a process for treating phosphorus-rich bones and rocks with acid, making it easier for plants to obtain, and soon the world's first human -ma...

Harvested medicinal plants are usually dried in special crop dryers, in lofts, or in the shade. To obtain essential oils and juices from certain medicinal plants only freshly harvested material can be used. Dried medicinal plants are used in pharmaceutical practice (for the preparation of infusions...
Plant resources gathered from the wild are important sources of livelihood needs, especially for low-income populations living in remote areas, who rely on these plants for food, fuelwood, medicine and building materials. Yadong County is a valley at the
On Earth, plant growth is sustained by soil, a complex mixture of organic matter, minerals, gases, liquids, and organisms, that is not found on any other known planetary body. However, the transport of soil to future space settlements is not logistically feasible. While establishing an in sit...
