Abstract

The increasing population and the problem of land use change that continues to increase raises the problem of food security. Government programs have been carried out such as the expansion of marginal land in coastal areas, namely saline land. The research objective was to assess the effectiveness of P uptake due to the aplication of humic acid and silica on lowland rice crop production. The research method was arranged in a randomized block design that was repeated 3 times. Size of planting 2x2 m2, 4 kinds of treatment include; a. control b. humic acid c. silica d. humic acid + silica. The results showed that the application of humic acid + silica had a significant affect the rice growth with an average plant height of 85,74 cm at 10 mst and rice production of 4,20 ton.ha-1. Humic acid + silica can also improve soil chemical properties : pH 6,95 CEC 40,24 and P nutrient 197,6. This is because the ability of humic acid to chelate by removing the Pbonds from the uptake of metal and silica elements can increase the P content in the soil into a from that is more available to plants.

Abstract

Cocoa pod have the potential to be used as an organic fertilizer because of the nutrient content in them. It was reported that 61% of the total nutrients in the cocoa pods are stored in the pod husks themselves. Liquid organic fertilizer derived from cocoa waste by combining EM-4 as a decomposer has an organic C content of 28.24%, a total N of 1, 64%, C / N ratio of 17%, P total 0, 98%, and K total 0.75%. Cocoa pod husk waste has the potential to provide added value to plantation products by further processing it as liquid organic fertilizer (POC) through a fermentation process. For this reason, this study aims to determine the effect of several levels of POC concentration obtained from the processing of cocoa husk waste and its combination with urea fertilizer doses on the growth performance of cocoa seedlings which include plant height, number of leaves, stem diameter and efficiency of N uptake of cocoa plants (ESN). This research was conducted in a greenhouse, Indonesian Coffee and Cocoa Research Center, Jember, and was compiled using a Completely Randomized Design (CRD) consisting of two factors used, namely the level of POC concentration (control, 0.25%, 0.50% and 1%) and the level of urea dose against the recommended dose (control, 10%, 25% and 50%). The analysis showed that the POC combination of cocoa and urea waste was able to increase the average plant height and diameter compared to the control. In addition, the combination of POC 2.5 ml / L and 10% dose of urea resulted in an increase in the efficiency of N uptake in tissues by 44.60%.

Abstract

The mineralization process is responsible for the availability of N in the soil. The purpose of this study is to examine the management of coffee land (Coffea L.) and climate on the rate of soil Nitrogen mineralization. In situ incubation research by implanting 15.5 cm long cylindrical pvc ring; diameter of 14 cm that has been perforated around it and a wire covering / net so that animals such as scorpions and snakes do not enter the hole. The research was arranged in factorial randomized block design which was repeated 3 times. Factor 1 : 3 types of land management and factor 2 : 4 types of organic matter. The level of N mineralization is evaluated against the levels of N-nitrate and N-ammonium soil. The highest NH4+ N concentration of 0.060% was found in the L1S3 treatment (first land, mixed ring) and the lowest NH4+ concentration in the L3S1 treatment (third land, control ring) 0.03%. NO3 concentration - interaction occurs with the highest NO3 concentration in the L2S3 treatment (second land, mixed ring) 0.092% and lowest NO3 concentration in the L1S1 treatment (first land, control ring) 0.013% with a BNT value of 5% at 0.023%. So the fastest nitrogen mineralization occurs in soils that get litter of shade plants (mixed / S3). The value of mineralization rate is strongly influenced by temperature, the increase in the value of mineralization rate due to temperature is due to the faster process of decomposition of organic matter.
