Pengaruh Kompos Ela Sagu dengan Mikroorganisme Antagonis Terhadap Kemasaman, P Tersedia dan N-Total Tanah pada Ultisols

Agricultural waste, such as sago ‘ela’ or sago extraction waste, can be used as an organic fertilizer to improve the physical, chemical and biological properties of the soil. In addition to organic fertilizer from sago ‘ela’, microorganisms can also be used to increase soil fertility. The purpose of this study was to examine the effect of sago ‘ela’ compost and antagonistic microorganisms in the process of changing acidity (pH and Al-exc), availability of P, and total N in Ultisols soil. The research took place at the Laboratory of Soil, Water, and Plant Analysis, Faculty of Agriculture, Pattimura University, Ambon, in June - September 2016. The experiment was carried out with a completely randomized design (CRD) with a factorial arrangement of 4 x 3, with 3 replications. The treatments of providing sago ‘ela’ compost consisted of: no compost (K0), 15 g/kg of soil (K1), 22, 5 g/kg of soil (K2), 30 g/kg of soil (K3). Inoculum provision of antagonistic microorganisms consisted of: without inoculum (A0), Trichoderma sp inoculum 20 mL (A1), and Azotobacter sp inoculum 20 mL (A2). The experiment used 3 replications. The results showed that soil pH was increased by compost and antagonistic microorganisms. However, the effect of compost does not depend on the presence or absence of antagonistic microorganisms and vice versa. Al-exc concentrations were reduced by compost and microorganisms, but the effect of microorganisms only occurred in the soil without compost and in the treatment of 15 g/kg of soil (K1). Above these compost doses, the effect of microorganisms was not significant. The concentrations of available P and total soil N were increased by compost and microorganisms, and the effect of compost was greater if accompanied by the application of Azotobacter sp.

Set Up

Azotobacter chroococcum based biofertilizers have been widely used in the production of environmentally agriculture. For commercial scale, cheap growth media for Azotobcter inoculant will affect the quality and price of liquid biofertilizer. Growth medium should support cell proliferation as well as its nitrogen fixation and phytohormone production. The objective of this study was to determine whether liquid organic fertilizer (LOF) containing low N can be used as a medium for scaling up A. chroococcum inoculant without lowering the survival of bacteria and its activity in N2 fixation and phytohormones production. LOF generally contains a complete nutrient although in a small quantities. Experiment was set up in completely randomized design which tested two types of commercial LOF. The results showed that both of LOF were only able to support cell growth up to 72 hours and at 96 hours cell viability began to decline compared to the control medium, free-N Ashby. At 72 hour total N and cytokinin concentration in LOF was lower than those in Ashby media. This study revealed that LOF could be used as A. chroococcum growth media, but without optimization of its composition, cell density and cytokinin content would be lower than those of inoculant in Ashby Media.

Biochar Amendment

A study was conducted to investigate the impact of biochar amendment on chemical properties and corn nutrient uptake in a sandy Podzol soil. Four rates of biochar (0, 5, 10, and 15 g kg−1) and two rates of inorganic fertilizer (0 and local recommendation rate for corn) were randomly applied to a completely randomized design with four replicates. Corn was grown for 45 d in a glasshouse using sandy Podzol. The increase in pH of the soil was concomitant with a decrease of exchangeable Al. The fertilized soil significantly increased total N, with a concomitant decrease in soil pH due to a N nitrification. Positive changes did occur in the soil due to biochar application, leading to a significant increase in dry matter yield and corn height. Corn N and K uptakes were significantly increased by the addition of biochar, but the same was not true for Ca and Mg. However, it was found that the concentrations of N, Ca, and Mg in the corn tissue were still lower than their critical level. Our results demonstrate that application of biochar alone is not able to supply enough nutrients for the healthy growth of corn.
