Abstract

Podsolic soil in South Kalimantan has a low fertility rate including pH, organic matter, cation exchange capacity (CEC), solubility P, and has a high solubility of aluminum (Al) and iron (Fe). It causes fixation P by Al and Fe in the form of Al-P and Fe-P, which makes P difficult to dissolve in the soil. Zeolite is an ameliorant that is capable of improving soil chemical properties based on its ability to carry out ion exchange, adsorption, absorb molecules, increase fertilizer efficiency, increase soil CEC, and the availability of Ca, K, and P ions, which can reduce aluminum content. The purpose of this study was to identify the pattern of relationships caused by application of activated natural zeolite on Podsolic soil against pH, CEC, available P, soluble Fe, and exchangeable Al. This study was a pot experiment weighing 0.5 kg of soil, carried out in a greenhouse and arranged using CRD a single factor . The incubation period was carried out for eight weeks with three replications. The results showed that there was a relationship between the zeolite dose activated against the available P (the linear regression equation Y = 0.6 + 0.032 X, R2 = 0.4969, and r = 0.7006*), while the doses of zeolite had no significant effect on pH, CEC, soluble Fe, and exchangeable Al.

Abstract

The study aimed to determine the effect of application fertilizer derived from animals (manure) or plants (green manure) on the supply and absorption of plant N, changes in pH, CEC, and suppressing Al solubility and to determine the best type of organic matter in supplying and absorbing plant N, change in pH, CEC, and suppress Al solubility. This study was carried out in the field and arranged using a single factor completely randomized design (CRD). The treatments applied in study were K0 = control, K1 = cow manure (50 g pot-1), K2 = goat manure (50 g pot-1), K3 = chicken manure (50 g pot-1), K4 = green manure for weed hair buns (50 g pot-1), K5 = rice straw green manure (50 g pot-1), K6 = gamal green fertilizer (50 g pot-1). The application of various organic materials can increase pH, CEC, available N, plant dry weight, N uptake of corn plants, and reduce Al solubility.

Abstract

As long as the issues with peat soil, particularly with some of its chemical qualities, can be treated properly, it has the potential to be utilized as agricultural land. Empty oil palm fruit bunches (EFB), which are produced by the size of oil palm farms, can be used to make biochar and EFB compost, which are then combined to create biokom, which can enhance soil structure and increase the availability of phosphorus in peat. Aspergillus oryzae-Tb7 is one of the phosphore solubilizing fungus (FPP) that aid in accelerating the release of accessible P. The byproduct of burning coal in a PLTU that is alkaline by nature and capable of raising soil pH to promote an increase in available P is known as coal fly ash (CFA). The goal of this study's conclusion was to ascertain the impact on the chemical characteristics of maize plants' uptake of P as well as soil pH, CEC, soluble Fe, and available P.A single-component, completely randomized design was used in this study (CRD). The factors A 0, which stood for "control without treatment," A1, "P fertilizer," A2, "P + Biochar fertilizer," A3, "P + CFA fertilizer," A4, "P fertilizer + Biokom + FPP," and "P fertilizer + Biokom + CFA + FPP," were tested. There were three repetitions of each therapy, yielding 18 trials. The findings show that the use of biokom, FPP, and CFA can improve P uptake, soil pH, CEC, and soil-accessible P while lowering plant dry weight and soluble Fe.

Abstract

Ultisols is the dominant soil type occupies dry land areas in Indonesia. This soil type is a great potential for the development of the agricultural sector in Indonesia. Constraints of physical, chemical, and biological properties of Ultisols must be considered in utilizing for optimal development of agricultural production. This study aimed to determine the effect of inorganic and organic fertilizers in soil pH, exchangeable-Al, CEC, plant dry weight, and N uptake of maize planted on an Ultisols. This research was carried out in February to June 2021 and conducted in a greenhouse and Soil Physics and Chemistry Laboratory, Department of Soil, Faculty of Agriculture, Lambung Mangkurat University. The data obtained from all observed variables were analyzed using orthogonal contrast. The results showed that the application of fertilizer, either inorganic and organic, were able to increase soil pH, but decreased plant N uptake and plant dry weight. The application of inorganic fertilizers increased soil pH more than the application of organic, but the N uptake and dry weight of plants increased more due to the application of organic fertilizers than the inorganic. The application of ZA fertilizer decreased soil pH more than the application of urea, although the changes in exchangeable-Al, CEC, N uptake, and plant dry weight were not different. The application of green manure was able to increase the exchangeable-Al content and reduce the N uptake of plants than the application of manure.

Abstract

Ultisols distributes spreadly in Indonesia, but this soil has low fertility. Therefore, the application of organic matter (OM) is a common management to increase this soil fertility. The purpose of this study was to determine the role of different types of OM (originated from animals and plants) on the availability of nitrogen, phosphorus, and potassium as well as nitrogen uptake in maize in Ultisols. Soil with a mass of 5 kg without organic matter (control), with the application of chicken manure, cow manure, swallow manure, kirinyuh, babadotan, and kalopo manure were incubated in experimental pots for two weeks at 60% field capacity. After the completion of the incubation period, soil sub-sampling was carried out for the determination of available N, available P and exchangeable K. Furthermore, in each experimental pot, corn seeds were planted, and the observations of dried-weight of corn and nitrogen uptake in corn were observed in a vegetative phase. The results showed that the application of different types of organic matter increased soil pH, nitrate content, exchangeable K, plant dried-weight and plant nitrogen uptake. The content of ammonium and available P was not affected by OM addition. The results also showed that OM derived from animals resulted in higher increases in pH and exchangeable K than those derived from plants. However, OM derived from plants resulted in higher increases in nitrate, plant dry weight and better plant N uptake than OM from animal waste. The results of this study show that the application of OM results in increases in some soil chemical properties, in which the degree of increases in soil chemical characteristics is controlled by the OM origin.

Abstract

Ultisol has problems such as soil acidity <5.5, high Al saturation >42%, low organic matter <1.15%, low nutrients such as 0.14% N, P 5.80 ppm, and low base saturation < 35%. Chicken manure is an organic material that alters soil pH and increases total N, total P, and P uptake. Coffee grounds can increase pH, N nutrients, organic matter, available P, prevent fungal growth. The purpose of this study was to determine the effects of feeding chicken manure and coffee grounds compost extract in increasing pH, increasing N availability, decreasing exchangeable Al, and increasing P availability of Ultisol. The research method used was a one-factor Completely Randomized Design (CRD). Factors tested were chicken manure, coffee grounds compost extract, and a combination of the two up to five treatments. K0 = Control, no chicken manure and coffee grounds compost extract; K1 = Coffee grounds compost extract 4 kL ha-1; K2 = Chicken manure 2 tons ha-1; K3 = Chicken manure 2 tons ha-1 + coffee grounds compost extract 4 kL ha-1; K4 = Chicken manure 4 tons ha-1 + coffee grounds compost extract 8 kL ha-1. Each treatment was replicated four times for 20 experiments. The results showed that the application of chicken manure and coffee grounds compost extract decreased soil pH, and soil exchangeable Al and increased soil ammonium, nitrate and available P levels.
