Root growth and development of maize (Zea mays L.) is an important process in determining grain yield. The effects combined fulvic acid (FA, potassium humate as FA source) super absorbent polymer (SAP) uses on root yield were studied. A 2×3 factorial field experiment was applied by combining two SAP doses (0, 45 kg ha-1) three rates 1, 2 g L-1) over yr. Super to upper 20 cm soil layer at sowin...

In order to improve the anti-seepage performance of cover, this paper proposed use super absorbent polymer (SAP) particles water storage capacity soil, and mixed them into soil build an SAP composite but law movement in which is not clear. paper, a series column model tests were carried out measure changes pore pressure volume content cover at different depths. The results showed that under ext...

application of soil conditioners for remediation of saline- sodic soils is one of the common methods for improving soil properties in arid and semi-arid regions. in order to study the effect of soil conditioners on retention of soil moisture content, an experiment was carried out based on randomized complete block design with three replications in a saline-sodic sandy clay loam soil. the treatm...

Detection and quantification of pathogens in water is critical for the protection of human health and for drinking water safety and security. When the pathogen concentrations are low, large sample volumes (several liters) are needed to achieve reliable quantitative results. However, most microbial identification methods utilize relatively small sample volumes. As a consequence, a concentration ...
