Effect of Coastal Sediment to Nutrient Availability and Maize Productivity on Entisols

Abstract

Entisols had a great potential for maize planting area expansion in increasing its production. The low soil fertility could be improved by application of coastal sediment. This current research examined the effect of different amount of coastal sediment on nutrient availability and maize production on Entisols, West Kalimantan. The research was conducted from July to November, 2013 (L 6 ) and 100 Mg ha -1 (L 7 ). The treatments were arranged by completely randomized design with 3 replications. Research results showed that 42 Mg ha -1 coastal sediment was the best treatment and able to increase soil nutrients availability and maize productivity. The provision of coastal sediment increased the availability of K, Ca, Mg and Na, also the availability of nutrients in accordance with the increase of the dosage of coastal sediment.

Application of Coastal Sediments and Foliar Seaweed Extract and Its Influence to Soil Properties, Growth and Yield of Shallot in Peatland

“…The addition of Ca in peat soil was expected from coastal sediment. According to Suswati, Sagiman, & Sulakhudin (2015), coastal sediment contains high of Ca about 14.62 cmol(+)/kg. Table 2 shows that without coastal sediment application the soil tends to have a higher CEC than with the addition of coastal sediment.…”

“…Coastal sediment has a pH value of 8, Ca and Mg content separately of 9.75 and 5.82 cmol(+)/kg, and CEC of 22.94 cmol(+)/ kg (Sulakhudin, Suswati, & Hatta, 2017). A study by Suswati, Sagiman, & Sulakhudin (2015) stated that the addition of coastal sediment at dose 42 t/ha enhanced the yield of corn. This dose can produce corn of 9.23 t/ha, higher than other treatments which only range between 7.59-5.00 dry grain t/ha.…”

Effect of combination of inorganic fertilizer and biochar-coastal sediment on nutrient availability and growth of corn plants in alluvial soil

“…Alluvial soils originate from parent material of sedimentary material that accumulates along the sides of rivers and beaches near estuaries. This soil has low of availability of nutrients, CEC and pH but high Al solubility so that it does not support plant growth [6].…”
