The effect of ameliorants on improvement of soil fertility in post gold mining land at West Kalimantan

Abstract

The application of ameliorant has been suggested to improve soil fertility and crop growth in post illegal gold mining (PIGM) lands. This study evaluated the effect of ameliorant types and semipermeable layer on properties of soil in PIGM lands and growth of sorghum. A field experiment employed two treatments, i.e. type of ameliorant and semi-permeable layer. There were four ameliorant types applied i.e., without ameliorant (M0); coastal sediment at a dose of 40 t/ha (M1); biochar at a dose of 4 t/ha (M2), and coastal sediment at a dose of 30 t/ha + 4 t biochar/ha (M3). The second treatment consisted of two levels, namely: without a semi-permeable layer (S0) and the semi-permeable layer of 20 cm depth from the soil surface (S1). The results showed that types of ameliorant gave different effect to soil properties. Application of coastal sediment at a dose of 40 t/ha significantly increased the contents of Ca and Mg, whereas application of biochar at a doses of 4 t/ha increased soil CEC. The semi-permeable layer did not significantly affect plant height and stem diameter of sorghum. The highest of sorghum growth was reached by application of coastal sediment at a dose of 30 t/h + biochar at a dose of 4 t/ha. The combination of coastal sediment and biochar from banana peels could complement each other to improve soil fertility in PIGM land.To cite this article: Sulakhudin, Suswati, D. and Hatta, M. 2017.

The Effect of Biochar and Cow Manual Fertilizer on Nutrition Upport and Production of Sweet Corn (Zea Mays L.)

“…The results of the soil pH analysis had very sour (3.89%) , very low C-organic (0.24 %), N-Total (0.03 %) very low, Nisbah C / N (8 %) low and P2O5 high (13.68 ppm). This relatively high available P content is in line with the results of research by Mastur et al, (2017) which showed that P-available in post-PETI soils from Monterado was high with value of 15.21 ppm / KTK value of 4.70 (cmol (+) kg-1) is very low, kandungan Ca 0.26 (cmol(+) kg-1) , Mg 0.17 (cmol(+) kg-1) , K 0.02 (cmol(+) kg-1) , Na 0.04 (cmol(+) kg-1) and alkaline saturation of 10.43% in very low-grade post-PETI soils and Fe content of 13.53 ppm which is high-priced. 2, it shows that the effect of manure application on N nutrient uptake tends to increase compared to controls.…”

“…The coastal sediment consisted of 10.20% sand, 51.85% silt and 37.95% clay with high pH value (8.13) and very high base saturation. Sulakhudin, Suswati, & Hatta (2017) shows that coastal sediment has a base saturation of 82.87%. The contain of potassium and sodium in the coastal sediment was very high, whereas the calcium was high.…”

“…According to Suswati, Sunarminto, Shiddieq, & Indradewa (2014), in addition, it has high of pH, coastal sediment as well as conceived high alkaline nutrients, so that it will increase the availability of alkaline nutrients (Ca 2+ , Mg 2+ , Na + and K + ), nutrient uptake and increase the growth of maize in peat soil. 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.…”

Arbuscular mycorrhizal fungi to enhance the growth of tropical endangered species Pterocarpus indicus and Pericopsis mooniana in post gold mine field in Southeast Sulawesi, Indonesia

“…Increased nutrient uptake by AMF in low fertility soils indicates that AMF can reduce fertilizer use. However, the applications of organic and inorganic fertilizers are strongly needed for planting activities on post-gold mining land (Muddarisna and Siahaan 2014;Sulakhudin et al 2017).…”
