In this research the effect of Super Absorbent Polymer (SAP) on the crop growth, wilting point, sunflower survival, water holding capacity, and irrigation interval was investigated. The experiment was conducted with different concentrations of absorbent hydrogel (Igeta): 0% (control treatment), 0.05%, 0.1%, 0.2%, and 0.3% (w/w). The soil textures were sand, loam, and clay. The experiment was a ...

In this study, the impact of some organic matters and a moisture super absorbent were investigated on available water and delay of permanent wilting point in a sample soil of Rasht landscape. In incubation stage, 12 Treatments including control (70% v/v soil with 30% of the composted manure) and various amounts of soil, municipal compost, composted manure, olives and rice wastes along with a su...

In this study, we investigated the effects of organic waste and moisture superabsorbent on the amount of available water and delay in moisture equivalent of permanent wilting point (PWP) in soil. In the first phase (soil incubation phase), 12 treatments were studied in a completely randomized design at the Soil Science Laboratory of Science and Research Branch, Tehran. The treatments c...

A METHOD FOR OBTAINING A CONTINUOUS MEASUREMENT OF SOIL MOISTURE UNDER FIELD CONDITIONS A has been devised for making in situ under field conditions a continuous measurement of soil moisture. It consists of imbedding in the soil a standardized block of CaSO4 (plaster of paris). The moisture content of this material varies directly with that of the soil. Since the dielectric constant of plaster ...

SOIL physical properties are important for plant growth, but it is necessary to separate factors that affect plant growth directly from those that affect it indirectly.Water, oxygen, temperature, and mechanical resistance are interrelated factors that affect plant growth directly. An appropriate soil-water-air environment is essential for healthy plant growth. Letey (1985) introduced a nonlimit...
