Highly Weathered Soils

The effect of broiler litter applications on chemical properties of three highly weathered soils of different mineralogy was evaluated. The soils included in the study were Coto (very fine, kaolinitic, isohyperthermic Typic Eutrustox), Consumo (fine, mixed, semiactive, isohyperthermic Typic Haplohumults), and Corozal (very fine, parasesquic, isohyperthermic Typic Hapludults). Five broiler litter treatments (0, 5, 10, 15 y 20 t/ha) were evaluated in a Complete Randomized Block Design with four replications. The soils were incubated for two months at room temperature (23° C). Broiler litter did not increase 3+ significantly the pH of the soils; however, soil exchangeable Al decreased 3+ in all soils as a result of broiler litter applications. Exchangeable Al in Coto soil decreased from 0.21 cmolc/kg in the 0 broiler litter treatment to 0.09 cmolc/kg in the 20 t/ha treatment, in Consumo soil from 1.08 to 0.19 cmolc/kg, and in Corozal soil from 7.57 a 5.76 cmolc/kg. The treatments also increased electrical conductivity of the soils, such an effect being more evident in Coto soil. The 20 t/ha treatment increased soil electrical conductivity of Coto by 74%, whereas for Consumo and Corozal soils the increase was only 55 and 54%, respectively. Available P content in Coto soil increased from 40 mg/kg in the check treatment, to 65 mg/kg in the 20 t/ha manure treatment. In Consumo and Corozal soils no significant change in available P was observed. This finding is indicative of the high P fixing capacity of these soils. It is suggested 3+ that soil exchangeable Al in Consumo and Corozal soils is reacting with P in the manure, forming aluminum phosphates and contributing to phosphate + 2+ fixation. Broiler litter application increased exchangeable K and Mg , but 2+ 2+ not exchangeable Ca , in the three soils; exchangeable Mn increased in Consumo and Coto soils.

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.

The Tropics

Biochar, a carbon-rich product of pyrolyzed biomass, has been used as an amendment to improve the properties of marginal highly-weathered soils in the tropics characterized by widespread phosphorus (P) deficiency. Alfisols derived from charnockite in Ekiti State are typically deficient in available phosphorus. Two alfisols from Ire-Ekiti and Ijan-Ekiti were amended with 0 (P-only), 5, 10 and 20% (w/w) biochars from maize stover (mB) and sawmill waste (sB) and incubated for 56 days with the addition of 60 mg kg-1 P in solution and a control without biochar and P-solution. Incubated soils were sampled fortnightly and analyzed for available P using Mehlich III extractant, pH, and electrical conductivity (EC) in water (1:2 w/v). Results show that biochar increased the soil pH by 1-2 units and EC from the native 0.02 to 8.37 dS m-1 with mB at 10 and 20%, causing soil salinity (EC > four dS m-1). Biochar increased available P to values ranging from 9.96 to 376.22 mg kg-1 compared to 2.93 to 7.64 mg kg-1 in control and 5.42 to 40.13 mg kg-1nin P-only treatments. The available P increased with days of incubation up to day 42 and followed by a slight decline, but the P in biochar-treated soils was significantly higher than other treatments. The mB significantly improved soil properties (soil pH, EC, and available P status), particularly at higher rates more than sB. The 5% mB in which the problem of salinity problem associated with higher rates is avoided should be recommended.

The objective of this work was to characterize the chemical properties of white oat (Avena sativa) caryopsis and to determine the adaptability and stability of cultivars recommended for cultivation in the state of Rio Grande do Sul, Brazil. The trials were carried out in the 2007, 2008 and 2009 crop seasons, in three municipalities: Augusto Pestana, Capão do Leão, and Passo Fundo. Fifteen cultivars were evaluated in a randomized block design, with four replicates. The contents of protein, lipid, and nitrogen-free extract were evaluated in the caryopsis. Cultivar performances for the measured characters varied according to location and year of cultivation. The cultivar URS Guapa showed high content of nitrogen-free extract and low contents of protein and lipid in the caryopsis. 'FAPA Louise' showed high content of lipid, whereas 'Albasul', 'UPF 15', and 'UPF 18' showed high content of protein and low content of nitrogen-free extract. There is no evidence of an ideal biotype for the evaluated characters, which could simultaneously show high average performance, adaptability to favorable and unfavorable environments, and stability.

Sugarcane production should be integrated with crop diversification with a view to competitive and sustainable results in economic, social and environmental aspects. The purpose of this study was to assess the influence of different soil uses during the sugarcane fallow period on the chemical and physical properties of eutroferric Red Latosol - LVef (Oxisol) and Acric Latosol - LVw (Acric Oxisol), in Jaboticabal, São Paulo State, Brazil (21º14'05'' S, 48º17'09'' W, 600 m asl). A randomized block design was used with five replications and four treatments, consisting of different soil uses (crops) in the sugarcane fallow period: soybean only, soybean/fallow/soybean, soybean/millet/soybean, and soybean/sunn hemp/soybean. After two soybean crops, the LVef chemical properties remained at intermediate to high levels; while those of the LVw, classified as intermediate to high in the beginning, increased to high levels. Thus, the different soil uses during the sugarcane fallow period allowed the maintenance of LVef fertility levels and the improvement of those of the LVw. Two soybean crops increased macroporosity in the 0.0-0.1 m layer of the LVef; reduced soil aggregates in the 0.0-0.1 and 0.1-0.2 m layers of both soils, and reduced aggregate stability in these two layers of the LVw. Planting pearl millet or sunn hemp between the two soybean growing seasons promoted the formation of larger soil aggregates in the surface layer (0.0-0.1 m) of the LVw.

ABSTRACTApplication of liquid organic fertilizer formula plus on degraded soil to improve the productivity of the land and chili (Capsicum annuum L.) productionSoil exploitation in large numbers occurred in the District Wanaraja of Garut Regency. Excavation of soil more than 2 meters from the top layer for the manufacture of red bricks has exceeded the ability of the soil to re-establish its structure. So that the soils, which were agricultural lands, can be classified as degraded soils with less fertility and chemical properties. Lans reuse for agriculture requires adequate recovery and fertilizer input. This study aimed to determine the formula of LOF (liquid organic fertilizer) plus used with NPK compound fertilizer on degraded soil to improve the soil productivity. The design used was a Simple Randomized Block Design (RBD) by 10 combinations of LOF plus treatment with NPK compound fertilizer as follows: A = Control (degraded soil, no fertilizer), B = 0% LOF + 1 NPK, C = 0.25% LOF + 1 NPK, D = 0.50% LOF + 1 NPK, E = 0.75% LOF + 1 NPK, F = 1.00 % LOF + 1 NPK, G = 0.5% LOF + 3/4 NPK, H = 0.5% LOF + 1/2 NPK, I = 0.5% LOF + 1/4 NPK, J = 0.5 LOF + 0 NPK, and K = 1 NPK of normal soil that all replicated three times. The results showed that the degraded soil of red bricks required concentration of LOF above 0.5% to 1% when applied with 1 dose of standard NPK. It is able to balance the uptake of nutrients P, Ca, and B and percentage of fruitset in chili commodities equivalent to normal soil.Keywords: Chilli, Liquid Organic Faertilizer (LOF), NPK, Soil degrededABSTRAKEksploitasi tanah dalam jumlah yang besar terjadi di Kecamatan Wanaraja, Kabupaten Garut.

Low soil organic matter, low nutrient availability and the higher soil pH (more than 8) are the major problem of agricultural practices in region of Toshka. An incubation trial at October 2019 was conducted to investigate the effect of potassium humate (KH) and micronic sulfur (MS) on some chemical properties of different soils (sandy clay soils, loamy sand and sandy soils). The used amendments (KH and MS) were added to the studied soil at 4 levels of each amendment i.e. 0.0, 0.25, 0.50 and 1.0%. A two way randomized completely block design and provided with three replications. Studied parameters were included soil pH, EC, exchange Na and the content of available - P and K. Results showed that, the MS application at 1% level caused a significant decrease in soil pH values compared with the KH application and control treatment. These reductions were more pronounced in case of soil B (loamy sand). Also, KH application gave an increase on exchange Na and available-K. While MS application was cause an increased in soil EC and available-P in the three soils under study. Moreover, the increases in the percentage of available – K with added of KH were higher than added of MS for soils under study. While the percentages of available-P with added of KH were higher than with added of MS for studied soils. It may be recommended to add KH and MS at a rate of 1% to improve the soil chemical properties. But the effect of application from MS has greater than KH to increase dissolved sodium salts on the form of sodium sulfate, which facilitates disposal during soil drainage.
