p> Total(68.5%) and air (32.1%) porosity of S1 were significantly higher than those of S0 (58.3% and 26.2%, respectively); higher proportions of SAP, on the other hand, reduced the porosity sharply. The high usability of super absorbent polymers (SAPs) in personal hygiene products and in minimizing environmental wastes and regulating the levels of chemicals in the air and water in applications such as wastewater treatment, air purification, construction, life sciences and other applications are driving the absorbent polymers market. The characteristics, properties, with a great prospect structure, water-absorbent mechanism and measurement methods of the SAP are described in this paper. This paper evaluated the effects of a starch-based super absorbent polymer (SAP) on the characteristics of soilless growth media. Taking the potato cultivar Longshu-3 as the object, this paper studied the tuber yield and chlorophyll fluorescence parameters under effects of different applications of super absorbent polymer and potassium fertilizer, aimed to approach the effects of applying super absorbent polymer and potassium fertilizer on the yield index and chlorophyll fluorescence parameters of dry land potato from the viewpoint of photosynthetic efficiency. https://ldony.top/0g6 indicated that super absorbent polymer and potassium fertilizer had direct effects on the potato plant chlorophyll fluorescence parameters, manifesting in the increase of photosynthetic efficiency, and thus, improved the tuber yield of upland potato.</p><p> The results indicated that using S.A.P controlled of relationship soil, water and plant, decrease water stress. Results showed that in comparison to CK treatment, I60S treatment significantly reduced soil bulk density and obviously increased soil total porosity and capillary porosity, indicative of 6.62%, 11.19%, 16.45% and 7.97% decreases in soil bulk density compared to the treatments of CK, I60, I30 and I30S, respectively. However, in the I30S treatment, less effect on the forest soil characteristics and the volume growth were observed than that in the I60S treatment. Additionally, the volume growth rate of the I60S treatment also reached the maximum, which had significant differences with other treatments (P0.05). The I60S treatment also evidently increased MBC and MBN contents and significantly enhanced microbial respiration, showing 13.89%, 24.24%, 41.38% and 12.33% increases in microbial respiration rate over the treatments of CK, I60, I30 and I30S, respectively. When dried for 56 h, the water contents in substrates S1, S2, and S3 were 3.3,7.7 and 9.8 times higher than that in S0.</p><p> Super absorbent polymers can absorb water up to a few hundred or even a few thousand times their own mass. Application of SAP at 30 kg ha−1 plus half of conventional fertilisation can reduce maximum (64.1%) nitrate leaching losses from soil. They carry nutrients in the soil as well as it is considered as a key element for increased fertilizers efficacy, with reduced nutrient losses. In different treatments, dynamic accumulation of dry matter and nutrient in F. chinensis seedlings could be well described by Logistic equation with different feature indexes. With the purpose of promoting water-saving irrigation and poplar yield, a field experiment of 5 treatments, i.e. CK (conventional border irrigation), I60 (60% conventional border irrigation quantity), I30 (30% conventional border irrigation quantity), I60S (60% border irrigation quantity co-applied with super absorbent polymers) and I30S (30% border irrigation quantity co-applied with super absorbent polymers) was designed and performed. However, there is little information on the effect of border irrigation measure co-applied with super absorbent polymer on the forest-tree plantation. In the meantime, border irrigation is also an efficient measure which has the advantages of low cost, simple operation and easy popularization. Therefore, it is speculated that super absorbent polymer co-applied with border irrigation should be an interesting thing, and investigating their appropriate proportion has important theoretic value and practical significance.</p><iframe src="https://www.youtube.com/embed/cDa4W8WXIKM" width="560" height="315" frameborder="0" allowfullscreen></iframe><p> Water Hydrogel polymer does not alter the chemical composition of soils on which it is applied, nor does it impair the action of applied biocides viz. The special physical structure, unique chemical composition and characteristics of high water absorption capacity allow super absorbent polymers to be widely used in water-saving agriculture, horticulture and other industries to relieve drought and reserve water for farmland, seedling protection and crop yield improvement. Our research spans over a multitude of industries including Energy, Technology, Manufacturing and Construction, Chemicals and Materials, Food and Beverages etc. Having https://ldony.top/0gE , we bring a rich and reliable experience that covers all kinds of research needs. We are trying to collaborate with the Krishi Vigyan Kendra (KVK) in different locations, proposing them to conduct a scientific study with our product on particular crops so that more scientific data about the amount of water or chemical fertilizer our product can save, effect of our product on the soil, and impact on yield can be measured,” says Puran.

That meant the IC water and SAP calculated by this new method was more accurate than the one without the mineral admixture considered, which was able to reduce the excessive IC water and SAP dosage.</p>
