Abstract

Azotobacter spp. Viabilities on Some Combinations of Carrier Media. The purpose of this research was to find suitable carrier media for the survival of Azotobacter spp. as a biological fertilizer, before being applied to the field. The method used in this research is explorative, by inoculating Azotobacter spp. Isolate on 4 types of carrier media, namely soil; cocopeat; wood dust and charcoal with a combination of the following: K1 (Land); K2 (soil + cocopeat); K3 (Soil + sawdust) and K4 (Soil + husk charcoal), which were repeated 3 times, so there were 12 experimental units. Analysis of N, P, K, C-organic and pH for soil media, while for cocopeat, wood powder and husk charcoal, an analysis of N and P, C-organic tissue and pH was carried out. The parameters observed were optical density at 2, 4, 6 and 8 weeks. The results showed that the survival of Azotobacter spp. in K4 carrier media (a combination of soil and husk charcoal) is more secure than other types of carrier media with optical density that has not decreased. Analysis of N and P for rice husk charcoal tissue gave the highest results, namely 1,680% and 1,351%, which were one of the supporters of this inoculant viability. Azotobacter spp. viability still guaranteed until 6 weeks incubation period, in several media, (soil + cocopeat), (soil + sawdust), and (soil + husk charcoal). The combination of media (soil + husk charcoal) gave the highest population increase at the 6 weeks incubation period.

Abstract

Improvement of Chemical Properties of Ex-Gold Mine Land Through Application of Rice Husk Biochar and Chicken Manure. Ex-gold mining land that have been degraded so that soil fertility is very low. Mining with an open system causes an increase in the oxidation of sulfuric minerals which reduces nutrient levels, so it is necessary to make efforts to increase nutrients through the addition of rice husk biochar and manure. The purpose of the study was to determine the role of rice husk biochar and manure to improve soil chemical properties. This study used a completely randomice design (CRD)with 6 treatments and 4 replications. The results showed that 100% manure treatments could increase soil fertility, when the soil pH was 6.28, total N 0.0072%, and available P 59.74 ppm. The best treatments for the organic C parameter is a combination of 50% rice husk biochar + 50% manure, which is 1.42%. Based on research, the addition of organic matter can improve the chemical properties of ex-gold mining land.

Abstract

The formulation of chicken eggshell waste with market waste compost to increase the yield of green mustard (Brassica juncea L.). Aims to find the best and environmentally friendly organic fertilizer formula to increase the yield of green mustard and improve some soil chemical properties. This research is a pot experiment in a greenhouse, using a simple randomized block design consisting of 7 combinations. Fertilizer formulas that were tried were: F0 (without treatment), F1 = (100 kg of shell + 10 tonnes of compost), F2 = (200 kg of shell + 8 tonnes of compost), F3 = (300 kg of shell + 6 tonnes of compost), F4 = (400 kg of shell + 4 tons of compost), F5 = (500 kg of shells + 2 tons of compost), F6 = (600 kg of shells + 0 tons of compost), and each treatment was repeated 4 times. The parameters observed included: maximum plant height (cm), fresh plant weight at harvest, oven dry plant weight, soil pH, C-organic content, CEC and soil Ca content at harvest. The data were analyzed statistically, tested for variance. If the effect of the treatment had significant, then continued with the 5 % Duncans test. The results of this study indicate that the treatment has a significant effect on plant height growth, fresh weight and oven dry weight of plants, as well as changes in soil chemical properties such as: C-organic, soil CEC, and soil Ca content. The fresh plant weight was obtained in treatment F2 (9.55 g), followed by F3 (9.37 g), and F1 (9.18 g) per pot. While the highest CEC was obtained in the F2 treatment (36.31 me 100 g-1) with a soil Ca content of 7.52 me 100 g-1. The best fertilizer formula from this study was found in the F2 treatment.
