The herbs grown are mainly bean and herbs. Herbs require large quantities of carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium and sulphur, as well as trace elements such as boron, manganese, zinc, iron and molybdenum. There are similarities, but also differences, in the amount of nutrients required for grass and legume pastures. There is a strong demand for nitrogen for herbs and a greater sensitivity to the reaction to nitrogen fertilizer applied. The soybean herbs are less sensitive to a herbivorous crop because of their co-inflicted nitrogen, which can only be applied to a small amount of nitrogen fertilizer before the root tumour is formed. And legume herbs are more sensitive to nutrients such as phosphorus, potassium and calcium than grasses. The variety and quantity of nutrients absorbed by pastures from the soil depend on soil conditions, the growth environment and the variety and yield of pastures. The nutrients absorbed by pastures from the soil are far from meeting their growth needs, and the nutritional needs of pasture growth are met only by scientific fertilization。

The application of herbicide-based fertilizers is carried out by application, stripping, layering, mixing, etc. When the soil is turned over, the fertilizer is spread evenly into the field and then soaked; the application is the opening of a ditch in the field, the application of the fertilizer into the ditch and the subsequent planting of the soil, the concentration of the fertilizer, its use in small quantities and its high fertility; the stratification is the combination of deep tillage, the application of organic fertilizers to the deep, and the application of high-quality and fast-effect fertilizers to the upper part of the soil, including through arable land, both to provide nutrients for pasture and fodder crops and to facilitate the rapid fertilization of the soil; and the mixing of quick- and slow-effect fertilizer, which can be adjusted to one another and provide adequate nutrients over time。
Fertilizers
Herbicide can be applied differently depending on the fertilizer characteristics chosen. Wretches or dens are the usual fertilization methods used for pastures, sowing them in the ravine, sowing the seeds on the spot, and sowing the seeds in the soil together with the seeds, or sowing the seeds in the fertilizer and seed tanks, respectively。
Following fat
Fertilizers used as herbs for fatting are mainly fertilizers, but are now better used in human urine or manure. Fertilizers are pursued in several ways, such as evacuation, stripping, lacquering, spraying, flooding and out-of-root fatting. Extra-fertilization concentrations should not be too high, and 30-70 grams of acre were applied to trace elements without harm to crops. China fertilizer net
