Soil nutrients are those essential nutrients that are mainly supplied by the soil. Push Ups,Yoga Push Up,Handstand Push Up,Wall Push Ups nantong pinli fitness co.,ltd , https://www.ntcnpinlifitness.com
1. The main source of soil nutrients. Humus contains not only nitrogen, phosphorus, potassium, sulfur, calcium and other macro elements, but also trace elements that can be released by microorganisms for crop absorption and utilization.
2, to enhance soil water absorption, fertilizer retention capacity. Humus is an organic colloid, which has strong water absorption and fertilizer retention capacity. Generally, the water absorption rate of clay particles is 50-60%, and the water absorption rate of humus is as high as 400-600%. The fertilizer retention capacity is 6-10 times that of clay particles.
3, to improve soil physical properties. Humus is a good cementing agent that forms agglomerate structure, can increase the looseness and aeration of clay soil, and change the loose state of sand. At the same time, because of its darker color, it can absorb sunlight and increase soil temperature.
4, to promote soil microbial activities. Humus provides abundant nutrients and energy for microbial activity, and it can also regulate soil acid-base reactions, thereby facilitating microbial activity and promoting soil nutrient conversion.
5. Stimulate crop growth and development. The humic acids, organic acids, vitamins and some hormones produced during the decomposition of organic matter have a good effect on the growth of crops, which can increase the respiration and absorption of nutrients and promote cell division, thereby accelerating the growth of roots and aboveground parts. The organic matter of the soil is mainly derived from the applied organic fertilizer and residual roots. Many social groups used fireweed washers, straw returning, cutting green manure, grass field rotation, grain fertilizer intercropping, green manure enrichment and other measures to increase soil organic matter content, make the soil more productive and more productive, and should be adapted to local conditions. Promotion.
The soil nutrient quick-measuring instrument is an intelligent all-round soil nutrient analysis instrument, which can effectively help farmers to understand soil nutrients in time and thus fertilize.
