3389 results about "Soil structure" patented technology

Soil structure describes the arrangement of the solid parts of the soil and of the pore space located between them. It is determined by how individual soil granules clump, bind together, and aggregate, resulting in the arrangement of soil pores between them. Soil structure has a major influence on water and air movement, biological activity, root growth and seedling emergence.

Fertilizer special for tea trees

The invention applies to the tea crop production, which can improve the soil structure and provide adequate moisture, oxygen and nutrition to improve the yield and quality in tea crop cultivation. The invention relates to a liquid fertilizer containing microorganisms, organic matters and inorganic matters. The fertilizer adopts biological technology and electrolysis technology which complement each other, takes micro-organisms and mineralized substances as additive, as well as combines with nutritional formula (nitrogen, phosphorus, potassium, sulfur, magnesium, calcium, silicon, boron, zinc, iron, molybdenum, bacterial protein, amino acid, humus, plant nucleic acid, B vitamins, active enzymes and unknown factors which promote crop growth), so as to provide adequate nutrition for crops and improve soil to make the soil conducive to tea crop cultivation. Through biotechnology, the micro-organisms in a dormant state are added to the fertilizer and are activated under favorable environmental conditions to decompose the animal and plant residues, pesticides, fertilizers, heavy metal residues and minerals in the soil so as to change the contents of nitrogen, phosphorus and potassium. Through electrolysis technology, the mineralized substance additive enables the soil to produce a chain reaction to moisture and oxygen supply, so as to gradually change the ion charge in the soil, increase the soil oxygen supply amount, improve the moisture infiltration capacity and strengthen the conditions for microbial activities.
