Effect of Some Fertilizer Formulas on Soil Chemical Properties and Yield of Green Mustard (Brassica juncea L.) in Subak Tegal Lantang, West Denpasar District. The aims of this study is to determine the effect of several fertilizer formulas on soil chemical properties and yield of green mustard (Brassica juncea L.) in Subak Tegal Lantang, West Denpasar District. This study used a Randomized Block Design (RBD) consisting of 6 treatments including controls and repeated 4 times with a total of 24 treatment plots. Fertilization treatment consists of three types of fertilizers, namely organic fertilizer, inorganic fertilizer, and biofertilizer. The fertilizer formula tested consisted of P0 = control (without fertilizer), P1= 5 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1, P2= 5 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1 + biofertilizer (1 cc / liter water / plot), P3= 10 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1, P4= 10 tons of compost ha-1 + 300kg Phonska ha-1 + 200kg Urea ha-1 + biofertilizer (1 cc / liter of water / plot), P5= biofertilizer with a concentration of 1 cc / liter of water / plot. The data from the observed parameters then analyzed statistically using analysis of variance (Anova) to determine the significance of the treatment. If it has a significant effect on the parameters observed, then it will be followed by the LSD test at the 5% real level. The results of study showed that the fertilizer formula treatment had a very significant effect on organic-C (P <0,01) and significantly affected the plant fresh weight (P <0,05), but had no significant effect on the acidity (pH), total-N, available-K, available-P, cation exchange capacity, base saturation, plant height, number of leaves, and plant dry weight. The P4 fertilizer formula gave the highest increase in soil organic-C content significantly by 2.99% or an increase of 66% compared to the control and gave the highest yield of fresh greens mustard by 23.64 tons ha-1.

<p>An improvement in soil chemical properties and crop development with silicate application has been confirmed in several plant species. The effects of silicate application on soil chemical properties and wheat growth were investigated in the present study. The experiment was carried out in 8-L plastic pots in a greenhouse. Treatments were arranged in a randomized block design in a 3 × 5 factorial: three soils [Rhodic Acrudox (Ox1), Rhodic Hapludox (Ox2) and Arenic Hapludult (Ult)] and five silicate rates (0, 1, 2, 4 and 6 Mg ha–1 of calcium/magnesium silicate), with four replications. The plant length, number of spikes per pot, shoot dry matter and grain yield, were measured after 115 days of wheat (<em>Triticum aestivum </em>L.) growth. Changes in the soil chemical properties (pH, H+ + Al3+, Al3+, P, K, Ca, Mg, Si, Cu, Zn, Fe and Mn) were analyzed after wheat harvest. Application of calcium/magnesium silicate reduces the potential acidity (H+ + Al3+) and Al3+ phytotoxic; and increases the soil pH, available Ca, Mg and Si, cation exchange capacity (CEC) and soil base saturation. Silicate application did not affect the available P, exchangeable K and availability of micronutrients (Cu, Zn, Fe and Mn) in the three soils. The application of calcium/magnesium silicate in an acid clayey Rhodic Hapludox improves the development and yield of wheat; however, the silicate application in soil with pH higher to 5.3 and high Si availability does not affect the agronomic characteristics and grain yield of wheat.</p><p><strong> </strong></p>

Fertile agricultural land encourages people to carry out agricultural cultivation activities. But in general, it has decreased soil fertility because its managed intensively without recycling of organic matter and has an impact on decreasing soil fertility chemically such as soil organic carbon and pH then leads to low productivity. Soybean is an agricultural product that necessary to develop because the demand for soybean consumption in East Java Province has always increased. However, Indonesia has not been able to fulfil this demand. One of the technology innovations that can be applied to improve soil fertility that has low organic matter and to increasing soybean production by providing input of quality organic fertilizer in the form of compost (Tithonia and Cow Dung). So this research is important to determine the effect of application cow dung compost and tithonia on soil chemical properties, the growth of soybean crops, and the correlations between soil chemical properties and soybean growth. This study used a randomized block design with 6 treatments and 3 replications. The result showed that the application of tithonia and cow dung compost shows a significant effect on soil chemical properties, plant height, and the number of leaves, but didn’t show a significant effect on the number of branches in every observation. Based on the correlation analysis, the results show a positive correlation between soil chemical properties and soybean growth.

The Impact

One effort that can be done to improve soil fertility and crop yields is fertilization. Fertilization using a mixed source fertilizer (MSF) is an option to overcome the impact of inorganic fertilizer use and organic fertilizer drawbacks. This study aims to evaluate the effects of MSF application on the chemical properties of Inceptisol and rice yields. A field experiment was conducted using a completely randomized block design (RCBD) with two factors and three replications. The first factor was the three formulas of MSF (F1, F2, F3) and the second factor was MSF doses (0, 2.5, 5, 7.5, 10 Mg ha-1). The results show that there is no significant difference on the total soil N, available soil P, plant height and total number of tillers of rice plants applied with the three MSF formulas. The increased MSF doses applied significantly improve the soil chemical properties of Inceptisol and rice yields. The application of 10 Mg ha-1 MSF increases total- N (57.89%), available-P (29.13%), exchangeable-Ca and -Mg (117% and 250%, respectively), plant height (40%) and total number of tillers (43.2%) in comparison to those without MSF application. There are interaction effects between formulas and doses of MSF on the amount of exchangeable-K, organic-C content, and CEC of the soil and rice yields. The application of 10 Mg ha-1 MSF F3 results in better effects on the amount of exchangeable-K, organic-C content and CEC of the soil, and number of productive tillers and rice yields than the application of other MSF formulas. The MSF can be used as an alternatif fertilizer that can improve Inceptisol productivity.
