And Chemical Properties

Organic farming is one of the management strategies that improve productivity of marginal uplands. The study aimed to: (1) evaluate effects of various organic-based fertilizers on the growth and yield of corn; (2) determine the appropriate combination for optimum yield; and (3) assess changes on the soil physical and chemical properties. Experiment was laid out in Randomized Complete Block Design, with 3 replications and 7 treatments, namely; T0=(0-0-0); T1=1t ha-1 Evans + 45-30-30kg N, P2O5, K2O ha-1; T2=t ha-1 Wellgrow + 45-30-30kg N, P2O5, K2O ha-1; T3=15t ha-1 chicken dung; T4=10t ha-1 chicken dung + 45-30-30kg N, P2O5, K2O ha-1; T5=15t ha-1 Vermicast; and T6=10t ha-1 Vermicast + 45-30-30kg N, P2O5, K2O ha-1. Application of organic-based fertilizers with or without inorganic fertilizers promoted growth of corn than the control. But due to high infestation of corn silk beetle(Monolepta bifasciata Horns), its grain yield was greatly affected. In the second cropping, except for Evans, any of these fertilizers applied alone or combined with 45-30-30kg N, P2O5, K2O ha-1 appeared appropriate in increasing corn earyield. Soil physical and chemical properties changed with addition of organic fertilizers. While bulk density decreased irrespective of treatments, pH, total N, available P and exchangeable K generally increased more with chicken dung application.

Management Interventions

Soil is spatially heterogeneous and needs site-specific management. However, soil nutrient information at larger scale in most cases is lacking. Consequently, fertilizer advisory services become dependent upon blanket recommendation approach. Subsequently, it affects yield and profitability. This study is aimed at explaining soil fertility heterogeneity in Wolaita zone, Southern Ethiopia. About 789 soil samples were collected to evaluate soil physical (color, particle size, and bulk density) and chemical properties (pH, OC, N, P, K, Ca, Mg, B, Cu, Fe, Mn, Zn, PBS, and CEC). The laser diffraction method for soil particles and mid-infrared diffused reflectance (MIR) spectral analysis for OC, TN, and CEC determination were employed. Mehlich-III extraction and inductively coupled plasma (ICP) spectrometer measurement were used for the remaining elements. The result based on principal component analysis showed that 52% of the total variations were explained by exchangeable bases, CEC, pH, available P, Cu, B, and particle sizes. Clay texture and acidic soil reaction are dominant. Soil parameters with the following ranges were found at low status: soil OC (0.2–6.9%), total N (0.01–0.7%), available P (0.1–238 mg/kg), S (4–30 mg/kg), B (0.01–6.9 mg/kg), and Cu (0.01–5.0 mg/kg). Besides, low levels of exchangeable Ca, Mg, and K (Mg-induced K deficiency) on 22, 34, and 54% soil samples, respectively, were recorded. The soil contained sufficient Fe, Zn, and Mn. In conclusion, the study aids in developing practical decision for optimum soil management interventions and overcomes lower productivity occurring due to fertilizer use that is not tailored to the local conditions. Overall, continuous cropping, low return of crop residues, and low and/or no fertilizer application might have caused the low status of N, P, K, S, B, and Cu. Therefore, application of inorganic fertilizers specific to the site, lime in acidic soils, and organic fertilizers are recommended to restore the soil fertility and improve crop productivity.

Abstract. Soetedjo IP. 2019. Various dosages of active powder of cassava improved sustainability of physical and chemical characteristics of Vertisol and Alfisol on dryland farming system. Trop Drylands 3: 29-33. Vertisol and Alfisol are two kinds of dominant soil in dryland farming system of East Nusa Tenggara and other areas with similar ecological conditions. However, both soils generally have a low content of some nutrients such as N, P, K, C organic, and are dominated by clay, high water saturated, and prone to Al, Fe, and Mn poisonings. Some studies reported that improvement practices by application of inorganic and organic fertilizers increased soil compaction and soil microbiology dormancy. An innovation product called active powder may improve soil microbiology activity and physical characteristics of soil, which might then improve the availability of soil nutrients. Research had been done to know the effect of various dosages of active powder to enhance the physical and chemical characteristic of Vertisol and Alfisol in dryland farming system in Kupang, East Nusa Tenggara. The research was a factorial treatment designed laid out in a Randomized Complete Block Design, and four replicates. The treatments employed were two types of soil (Vertisol and Alfisol) and various dosages of active powder (0, 100, 200, and 300 g ha-1). Parameters observed were subjected to ANOVA and was followed by a Least Significant Different Test at 0.05 level. Results of the research showed that dosage of active powder of 300 g ha-1 was able to improve number colony of soil bacteria, soil porosity, soil bulk density, total N, P availability, and K availability. Generally, the physical and chemical characteristic of Vertisol was better improved than Alfisol. The yield of mungbean was significantly affected by the dosage of the active powder of 200-300 g ha-1 in which yield of mungbean grown at Vertisol was higher than that at Alfisol.

Declining soil fertility and nutrient availability are one of the major threats to reducing crop productivity in Nepal. A field experiment was conducted to assess the potential of biochar (10 t ha-1) blended with organic and inorganic fertilizers on improving soil fertility and radish productivity in Morang district, Nepal. Biochar was prepared from locally available twigs, branches, and wood using the soil pit “Kon tiki” method. The experiment was laid out in Randomized Complete Block Design with 7 treatments having four replications viz., control (CK), biochar (BC), biochar + cattle manure (CM), biochar + poultry manure (PM), biochar + cattle urine (CU), biochar + commercial biofertilizers (BF) and biochar + inorganic fertilizers (urea-N). The nitrogen rate used in all the treatments was equivalent to 100 kg ha-1. The agronomic effect of biochar blended organic amendments was compared with control and inorganic urea-N treatments.  Biochar amended plots showed significantly higher soil pH (6.5), organic matter (4%), total N% (0.8%), available P (80.1 kg ha-1), and K (203.6 kg ha-1) compared with control. CM increased marketable yield by 320% (63 t ha-1) and biomass yield by 198% (100 t ha-1) compared with control (15.0 t ha-1 and 34 t ha-1) of marketable and biomass yield, respectively. CM increased marketable yield by 44% compared with the urea-N treatment (44 t ha-1). Moreover, net return was observed highest with CM treatment among all the organic and urea-N treatments. The study suggests that the combination of biochar with locally produced cattle manure has the potential to increase radish productivity and could compete with mineral nitrogen fertilizers while producing similar or even higher crop yields and economic returns.

The Impact

<p>Acid soil is commonly grown with cassava, which in general, tolerate low soil  fertility and aluminum (Al) toxicity. However, without any improvement efforts such soil will become worse. Intercropping cassava with <em>Brachiaria decumbens </em>(BD) which adapts to acid soil and tolerates low fertility soils as well as application of arbuscular mycorrhiza (AM) and organic matters are among the important efforts to rehabilitate this soil. The experiment was conducted to  examine the impact of BD, AM, and potassium (K) enriched rice straw compost on exchangeable Al, available K, and stability of soil aggregates. Experiment was arranged in a completely randomized design with three factors and three replications. The first factor was BD as cassava intercropping, the second factor was AM, and the third factor was 2 t ha-1 rice straw compost enriched with 0 kg, 50 kg, 100 kg, and 200 kg KCl ha-1. Brick pots (1 m length x 1 m width x 0.45 m depth) filled with Kanhapludult soil was used for growing cassava in which row of BD was planted at 60 cm from cassava stem. K-enriched rice straw compost and AM (10 g per stem) were applied around cassava stem at 2 and 12 days after planting, respectively. BD was cut every 30 days and the cutting was returned to the soil. Soil exchangeable Al was analyzed at 0, 3, 6 and 9 months after planting (MAP), while Al and K contents as well as aggregate stability were measured at 6 MAP. The results showed that planting BD decreased 33% exchangeable Al, which means that the root exudates of this grass was effective in detoxifying Al3+. Treatment of BD and/or in combination with AM was effective in preserving K added to the soil, increasing total polysaccharides, and improving soil aggregate stability. This indicated that planting BD and applying AM and Kenriched rice straw compost improved acid soil fertility, and therefore can be recommended in cassava cultivation.</p>

Windrows of municipal yard and landscape waste at three commercial composting sites in California were sampled at ≈3-week intervals through 12 to 15 weeks of composting to observe changes in physiochemical and biological characteristics of importance to horticulture. Initial C, N, P, and K content averaged 30%, 1.3%, 0.20%, and 0.9%, respectively. Carbon concentration declined rapidly through the first 6 to 9 weeks, while N, P, and K remained relatively stable throughout the sampling period. Few viable weed seeds were found in any compost. A high level of phytotoxicity, as measured by a tomato (Lycopersicon esculentum Mill.) seed bioassay, was observed at only one site; overall, the degree of phytotoxicity declined with compost age. Short-term net N immobilization (in a 2-week aerobic incubation) was observed in nearly all samples, with an overall trend toward decreased immobilization with increased compost age. In a 16-week pot study in which fescue (Festuca arundinacea Shreb.) was grown in compost-amended soil, net N mineralization averaged only 2% to 3% of compost total N content. Neither composting site nor duration of composting significantly affected either N mineralization rate or fescue growth. Growth of vinca (Catharanthus roseus Don.) in a blend of 1 compost : 1 perlite increased with increasing compost age. Overall, at least 9 to 12 weeks of composting were required to minimize the undesirable characteristics of immature compost.

Increased productivity of red chili plants is done to meet consumer demand which continues to increase by increasing cultivation techniques, one of which is fertilization. So far, farmers on dry land only rely on the use of high amounts of inorganic fertilizers. While the use of inorganic fertilizers continuously without being balanced with the provision of organic fertilizers can reduce the quality and fertility of the soil. This extention service aims to (1) provide understanding and enrich knowledge to farmers in the dry land of North Lombok regency to use a combination of organic and inorganic fertilizers in the cultivation of red chili, (2) practicing red chili cultivation techniques by giving a combination of organic and inorganic fertilizers. Community service was carried out within a period of six months to the "Tani Tulen" farmer group partners in Sambik Rindang hamlet, Salut village, Khayangan sub-district, North Lombok district. The approach method was used, participatory with the target empowerment process includes: (1) counseling; (2) the practice of planting red chilies with a combination of inorganic fertilizers. The results shows that (1) an increase in understanding farmers about the importance of using manure (compost) in increasing soil fertility, (2) the used of manure of 5 tons/ha combined with 350 kg Urea, 300 kg SP-36, and 200 kg KCl provide good growth in red chili plants.

Lettuce and Moringa are recently popular vegetable crops because their demand improves significantly, and their development lead to dry land because its potencial in Indonesia is still high.  The use of dry land should be followed by applying inter cropping technique in order to make plant micro climate becomes more favourable. In addition, low soil fertility and intensive ussage of inorganic fertilizers makes the application of organic fertilizers imperative. The objective of the research is to investigate the type of organic fertilizer giving high yield of lettuce and moringa cultivated using inter cropping technique in dry land. The results showed that the organic fertilizers applied improved the plant growth and yield, and also improved the land equivalent ratio (LER).  The highest LER was showed by apllication of Organox, followed by  Bio Extrim and Biota Plus, and the lowest one showed by without organic fertilizer application.

<em>Using acid soil as a cacao seedling medium limits the seedling growth due to low fertility, thus necessitating soil ameliorant treatment to improve its chemical, physical, and biological quality. This study aimed to investigate the effect of cacao husks as organic fertilizer and biochar on chemical and biological properties of seedling media and cacao seedling growth, was conducted in Soil Biotechnology Laboratory and Soil Fertility Laboratory, Bogor Agricultural University and Pakuwon Experimental Station at Indonesian Industrial and Beverage Crops Research Institute (IIBCRI), Sukabumi, from June 2014 until February 2015. Completely randomized design (CRD) was used in the factorial treatment with three factors: (1) organic fertilizer treatment (without organic fertilizer and with organic fertilizer 10% of the weight of seedling media), (2) the types of biochar (rice husk and white albizia wood), and (3) the doses of biochar (0%, 1%, 2%, 4%, 6% of the weight of seedling media), with three replications respectively. Observation was on chemical and biological properties of the soil and seedling growth.  The results showed that organic fertilizer or albizia wood biochar application significantly improved C-organic and  C/N ratio. Increasing the dose of biochar or organic fertilizer application raised the pH, total N, and microbes respiration, whereas  without organic fertilizer was linearly able to improve total population of microbes but not the dry weight of cacao seedling. The combination of biochar and organic fertilizers increased the stem diameter and dry weight of cacao seedling.</em>
