Dynamic of Saline Soil Cations after NaCl Application on Rice Growth and Yields
Saline soil cation dynamic is determined by the proportion of salt cations dissolved either acidic or alkaline. Common base cations in saline soil are in the proportion of Na > Ca > Mg > K. They affects the availability of water, nutrients, and plant growth. The six level of NaCl...

| Summary: | Saline soil cation dynamic is determined by the proportion of salt cations dissolved either acidic or alkaline. Common base cations in saline soil are in the proportion of Na > Ca > Mg > K. They affects the availability of water, nutrients, and plant growth. The six level of NaCl were 0, 15, 30, 45, 60, and 75 mM and two types of soil (saline and non saline) from Gununganyar and Mojokerto were evaluated to soil sample cations taken from depth of 0-5, 5-10, 10-15, and 15-20 cm. Rice growth and yields were measured. The experiment indicated that increasing doses of NaCl increased the soil Na after rice harvest and decreased K, Ca and Mg contents, both of non-saline and saline soil, decreased of rice growth and yield (straw, grain, number of tiller). NaCl up to 30 mM caused highest Ca:Mg ratio, about 8, suppressed nutrient available, inhibited root growth and reduced nutrient uptake. |
