The Difference

This study aimed to examine Organonitrofos Plus fertilizer (OP) on sweet corn (Zea mays Saccharata L.) and its effect on changes in soil chemical properties of Ultisols. Organonitrofos Plus fertilizer is an enhancement of Organonitrofos fertilizer enriched with microbes at the beginning of the manufacturing process. Research was conducted in the greenhouse of Integrated Agricultural Laboratory of Lampung University. Treatment applied was a factorial of 4 × 2 × 3 with three replications in a randomized block design. The first factor was the dose of OP fertilizer (0, 10, 20, 30 Mg ha-1), the second factor was the dose of inorganic fertilizers (without inorganic fertilizers, and with inorganic fertilizers, namely Urea 0.44, 0.28 SP-36 and KCl 0.16 Mg ha-1), and the third factor was the dose of biochar (0, 10, 20 Mg ha-1). By a single OP fertilizers, inorganic fertilizers, and the interaction between the OP and the inorganic fertilizers increased the weight of dry stover, cob length, cob diameter, cob with husk and cob without husk of corn. OP fertilizers which are applied in Ultisols can improve soil fertility and increase corn production so that OP fertilizer can lessen the use of inorganic fertilizer and can be used as a substitute for inorganic fertilizer. RAE values were highest in treatment of O4K2B2 (30 Mg OP ha-1, with inorganic fertilizer, 10 Mg biochar ha-1) that was equal to 181%, followed by O2K2B3 (10 Mg OP ha-1, with inorganic fertilizer, 20 Mg biochar ha-1 ) with the difference in RAE value of 0.5%.

Rice Husk Biochar

Rice husk biochar and compost application are expected to improve soil chemical properties such as pH, organic carbon, and available P in Ultisol, which in turn improves crop growth and P uptake by plants. The purpose of this research was to analyze the effect of the combination of rice husk biochar and compost on the soil chemical properties (pH, organic carbon, and available P), maize growth, and P uptake by maize in an Ultisol. The research used a Randomized Block Design with six treatments (P0: control; P1: 4 t biochar ha-1; P2: 30 t compost ha-1; P3: 4 t biochar ha-1 and 30 t compost ha-1; P4: 8 t biochar ha-1 and 30 t compost ha-1; P5: 4 t biochar ha-1 and 60 t compost ha-1) and four replications. The result showed that the combination of 8 t rice husk biochar ha-1 and 30 t compost ha-1 showed a significant effect on increasing pH, organic carbon, and available P in an Ultisol, increasing the height of maize crops at 4 and 6 WAP (weeks after planting). However, it had no effect on the number of leaves and showed an effect on the increase in P uptake of maize crop.

AbstractAlthough application of organic fertilizers has become a recommended way for developing sustainable agriculture, it is still unclear whether above-ground and below-ground crops have similar responses to chemical fertilizers (CF) and organic manure (OM) under the same farming conditions. The current study investigated soil quality and crop yield response to fertilization of a double-cropping system with rapeseed (above-ground) and sweet potato (below-ground) in an infertile red soil for 2 years (2014–16). Three fertilizer treatments were compared, including CF, OM and organic manure plus chemical fertilizer (MCF). Organic fertilizers (OM and MCF) increased the yield of both above- and below-ground crops and improved soil biochemical properties significantly. The current study also found that soil-chemical properties were the most important and direct factors in increasing crop yields. Also, crop yield was affected indirectly by soil-biological properties, because no significant effects of soil-biological activities on yield were detected after controlling the positive effects of soil-chemical properties. Since organic fertilizers could not only increase crop yield, but also improve soil nutrients and microbial activities efficiently and continuously, OM application is a reliable agricultural practice for both above- and below-ground crops in the red soils of China.

Rice Husk Biochar

The maize crop is an important commodity other than rice in Indonesia. Maize production reached 30 million tons in 2018. Efforts that can be made to increase maize production on Ultisols in Indonesia is by the application of biochar rice husk and compost. Biochar that has a high affinity for nutrients does not experience decay in the soil for decades, while compost can improve soil chemical properties by increasing nutrient content. The purpose of this study was to analyze the effect of the application of a combination of rice husk biochar and compost on soil chemical properties, N uptake, and growth of maize on an Ultisol. This study was conducted with six treatments. The results showed that the application of a combination of rice husk biochar and compost had an effect on increasing the C-organic and N-total in soil, but it did not affect the C/N of the incubated soil. Application of a combination of 8 t rice husk biochar ha-1 and 30 compost ha-1 significantly improved plant height, dry weight, and N uptake of maize plants.

Abstract The use of inorganic fertilizers with high doses is not recommended in the sustainable maize production program. The present study aimed to evaluate soil chemical properties and growth of maize plants treated with several types of manure to reduce the use of chemical fertilizers in sandy soil. An experiment was conducted in dryland with pumped deep-well water in Gumantar Village, North Lombok Regency, from May to July 2021. There were three types of manure tested: cow, poultry, and goat manures (20 ton/ha) treated with and without BeKa decomposer. All the manure treatments received 75% of chemical fertilizers applied in the control treatment (500 kg of urea and 380 kg/ha of NPK Phonska). The treatments were arranged in a randomized block design with three replicates. The results showed that the poultry manure treatments, with and without decomposer, increased soil pH significantly. This increase improved soil chemical properties, such as available P and K. Plant height, stem diameter, leaf area index at silking, and total N in leaf tissue, were not significantly different among the treatments. These results showed that the application of manures, with or without decomposer, could substitute 25% of the inorganic fertilizers needed by maize plants grown in sandy soil.
