Properties Of Soil

High input of chemical fertilizer causes land degradation on agriculture. This research is experimental which aims to analyze degree of acidity and macro-nutrients in mussel shell, and analyze chemical properties of soil before and after application of mussel shell suplement. The research was conducted during July to September 2020 at BPTP Laboratory, Narmada West Lombok. Data were analyzed descriptively. The results showed that mussel shell (Pilsbryocomcha excilis) had pH and macro-nutrients potential as an ecofertilizer. Soil chemical properties increase after application of mussel shell (Pilsbryocomcha excilis) supplement. Key words: mussel; shell; soil enhancer; suplement

Dung Decomposition

The effect of dung from cows grazing low and high input systems (2 cows/ha, 35 kg P/ha; 4 cows/ha, 140 kg P/ha) on soil chemical properties in temperate dairy pastures was investigated. Dung was used to create pads, and their effect on soil at 2 depths compared with control areas to which nothing was applied. Most dung had decomposed after 40 days in autumn, and was completely degraded by Day 60 in this temperate environment. Large quantities of the nutrients P, K, Ca, Na, Mg, and S were applied to the soil in these dung pads. The mechanism of movement of these nutrients from the pads into soil appeared to be based on their solubility in water. Phosphorus did not leach from the pads but was incorporated into the soil with the decomposing pad. Calcium, Mg, and S concentrations declined slowly in the decomposing pads. On the other hand, K and Na appeared to leach from the pads, as significant decreases in concentrations occurred during decomposition. Soil pH (1:20 soil:water) decreased under dung pads, although the effect did not last beyond 60 days and was linked to the observed increase in soil EC with depth. Extractable P and K increased considerably in soil under dung pads, but only in the upper 0–5 cm layer. Soil exchangeable aluminium and total organic P were not affected by the presence of dung pads. These results are discussed in relation to nutrient cycling in temperate Australian dairy pasture soils.

Natural peat swamp forests converted can alter the soil chemical properties. This study aims to determine the extent to which changes in soil chemical properties that occur after the conversion of land from peat swamp forest to palm oil plantation, HTI Acacia crasicarpa, and sago plantation and to know which types of plants are sustainable on peatlands. The results showed that soil pH increased after the change of land function. While the water content decreased. Chemical properties such as C-organic, ash content, CEC, alkaline saturation, macro nutrients (NPK) and bases can be changed also undergo changes after undergoing landuse changes, but no violations based on the law made by the government in pp No 25 of 2000 on the criteria of peatland damage and government regulation no. 150 of 2000 on the control of soil damage for biomass production. Sago is the most sustainable plant compared to others due to changes in soil chemical properties not too much different from other landuse although planted in the long term.
