Keywords: QUEFTS, recommendation, site spe-cific, yield INTRODUCTION Nutrient Use Efficiency in Maize in Indonesia and in almost countries in Asia is considered low which mainly relates to inappropriate management Maize growers need balanced crop nutrition to maximize its yield potential and get the most out of their fertilizer investment. A study on the impact of providing site-specific fertilizer recommendations on fertilizer usage, productivity and welfare outcomes in Ethiopia shows that targeted fertilizer recommendations encourage fertilizer investments and lead to improved maize productivity outcomes. Other factors, such as maize variety potentials in nutrient utilization, rainfall pattern, and disease occurrence should be considered as well. Maize is a major crop for farmers in many parts of the world and a staple food for many subsistence farmers in the developing world. AN: 200 kg/ha. ABSTRACT: Site specific fertilizer recommendations optimize crop production while minimizing nutrient losses. Phosphorus and potassium were applied just before sowing maize. If the soil test value is less than 6.0 mg/kg or ppm apply sulfur as recommended. Rate. . Efforts to improve the yields of staple cereal crops like maize and rice at scale in Africa remain seriously hampered by the effects of poor soil fertility. STCR Fertilizer Recommendation (kg ha-1) N P 2 O 5 K 2 O N P 2 O 5 K 2 O . 3-N (from soil test report) = 40 lb N/acre Fraction of N in urea fertilizer (46-0-0) = 46% = 0.46 lb N/lb urea.

Zinc and Iron This paper took DongChangFu district, LiaoCheng city, Shandong province as an example, established a Geographic Information System (GIS) based fertilizer recommendation . of soil test crop response based phosphorus fertilizer recommendation for maize under farmers' condition. sample do not correspond to government mineral fertilizer recommendations for maize growers in the region, which are appropriate for only 0.5 percent of the farmers in our sample,5 Our results indicate that national regional-level fertilizer recommendations are not serving the needs of many small farmers. Abstract. According to the University of Mississippi, you can also apply potassium fertilizer in the fall because, like phosphorus, potassium is relatively immobile in most soils. This study was conducted to identify soil fertility constraints of Reddish Brown Earth (RBE) in DL 1band Reddish Brown Latosolic (RBL) soil in IM 3cand to formulate site specific fertilizer recommendations for Maize (Zea mays L.). However, take-up rates were over 75 percent in treatments T1, T2 and T3all of which included subsidies to purchase recommended fertilizers. Fertilizer Recommendations Arriving at a correct fertilizer recommendation depends upon . To address this problem, fertilizer recommendations have mainly focused on measuring soil properties and regulating N nutrient supply based on the residual nitrate-N concentration in soil [ 4, 5 ]. The standard fertilizer recommendation for maize consists of 150 kg ha 1 NPK 14-23-14 and 50 kg ha 1 urea (Dugu 2010 ). Abstract. The lack of adequate information to base an effective fertilizer recommendation upon often results in inefficient nutrient use by crops and low crop yields. The crop is cultivated in all five NRs, NRs II and III accounting for about 84 percent of total maize production. The study found that plot-specific fertilizer recommendations based on on-site soil tests, paired with subsidies to purchase fertilizer, can improve farm productivity and profits. Made with Summer Project 2021 . The three most widely used fertilizer recommendation philosophies are the following: The Sufficiency Level of Available Nutrient (SLAN), also called the Percent Sufficiency concept or the Crop Nutrient Requirement (CNR) concept. Maize (Zea mays L.,) is an important smallholder crop grown in Ethiopia. For urea: Nutrient Expert for improved fertilizer recommendations for maize in sub Saharan Africa Evaluation of nutrient omission trials in Ethiopia The Nutrient Expert (NE) decision support tool has been successfully adapted for use in developing fertilizer recommendations that address wide diversity of soil and climatic conditions in Ethiopia, Nigeria . 7. L. 500 kg/ha. 3- Foliar applications of micronutrients may be applied 1-2 times per year. fertilizer 1 to 3 bags/ha 2 to 5 bags/ha 5 to 7 bags/ha 6 to 10 bags/ha (high N) e.g (50 to 150kg/ha) (100 to 250kg/ha) (250 to 350kg/ha) . As for example, wheat, paddy, oat may be put in one group and maize, jowar, sugarcane may be put in another group on the basis of their behaviour towards Soil test values. Not controlling for other covariates, the average maize grain yield without fertilizer use was 1100 kg/ha compared to 1475 kg/ha with fertilizer use. Fertilizer recommendations, application rates and timing. Fertilizer use recommendations The fertilizer requirements of crops have been researched extensively in South Africa. 2. www.iita.orgA member of CGIAR consortium Introduction: Demand . a 'Fertilizer Recommendation Committee' comprising of a dedicated team of soil scientists within NSSRC and NSAF experts was formed to develop site-specific fertilizer recommendations using the Soil-SMART . Significant reduction in N application in Corn with Multicote AgriRead more. Rate. If the maize price goes up with a mere R250 per tonne (R2 500/ton), profitability will increase by 14.3%. It seems to have inadequate P. It is well-balanced for S, Zn, and B, which are deficient in most potato-growing areas. The chart in Table 6 indicates a recommendation of 150 pounds of N per acre total requirement. The core of the fertilizer recommendation method in Nutrient Expert for Hybrid Maize is based on yield response and agronomic efficiency (AE). Over half of the required nitrogen (15 days before and after flowering), phosphorous and magnesium, and 80% of potassium, is taken up before the crop reaches the generative growth stages. R.V. Field name: Manure (if applied): Previous cropping: Fertiliser Recommendations Kg/Ha (accounting for any manure deductions): SNS: The lack of adequate information to base. . Cabbage. For preparing the fertilizer recommendation norms for each class of soil test values, (low, medium, high) crop response curves are to be prepared. Using the fertilizer application rate formula, you can calculate the amount of urea and phosphorus needed to satisfy the fertilizer recommendation of the maize plant. balanced fertilizer recommendation show that QUEFTS model is a valuable tool for site-specific fertilizer recommendation. Farmers who only . The district is located at an average The most commonly used fertilizer is NPK 15-15-15, the suitability of which is much debated for maize. If K is needed, starter N+K2O should be limited in the fertilizer band to prevent salt injury. Compound. Results determined that balanced fertilization with nitrogen, phosphorus, and potassium (NPK) doubled both maize and rice yields (i.e., from 2 to 4 t/ha) compared to . A generic but flexible and location-specific fertilizer recommendation method is necessary due to inappropriate fertilization in China. As conventional methods to generate fertilizer recommendations are time consuming, we will develop a machine-learning approach for a site-specific fertilizer recommendation strategy that will be relevant for all actors involved in maize production in Ghana, while accounting for uncertainties in model predictions. Applications of up to 246 kg ha -1 phosphorus (P) (approximate current cost equivalent to 3.5 tonnes of white maize) is recommended depending on the yield expectation, application method, soil texture and effective depth of sampling. At planting. Fertilizer recommendation methods based on soil testing can maximize the use of local soil nutrients while maintaining the crop yield and improving the nutrient utilization efficiency from fertilizers ( Chuan et al., 2016; Cui et al., 2008 ). Highlights from the study. Available Soil Information Find us. CALCULATIONS: Fallow-spring wheat Recommended fertilizer N = recommended N . response-team-fr@gmail.com The standard fertilizer recommendation for maize consists of 150 kg ha . The main fertilizer recommendation represents the total nutrients required/recommended for successful crops. Soil Health. NE was effective as a simple and cost-effective decision support tool for fine-tuning fertilizer recommendations to farm-specific conditions and offers an alternative to soil testing, which is hardly . A maize yield of 4 tonnes per hectare (t/ha) at a price of R2 250/tonne will earn a profit of 28.6% (at a production cost of R7 000/ha). Description of the Study Area Chora district is located at 519 km from the capital city of Ethiopia, Addis Ababa and 36 km from Buno Bedele zonal capital town, Bedele. Top-dressing. Application of sulfur is not required if test value is greater than 6.0 mg/kg or ppm. The fertilizer recommendation could be used for quantifying crop nutrient requirements to optimize nutrient management. Regional fertilizer recommendation is urgent needed for the National Soil Testing and Fertilizer Recommendation Program, which started at 2005 and has already covered most counties of agricultural production area in China. A new fertilizer recommendation method, Nutrient Expert (NE) for Hybrid Maize, was developed using maize datasets from 2000 to 2010 in main maize production areas. 119. In the SLAN approach, the soil test indices are interpreted as very low, low, medium, high, or very high, and an . Crop and site-specific fertilizer recommendations are developed using information from: soil testing tissue analysis specific requirements for . If the price remains the same, but the yield increases with 1 t/ha with an increased production cost of . Overall, fertilizer recommendations generated with NE maintained high maize yield, but at a lower fertilizer input cost than conventional methods. results and lead to higher fertilizer costs, lower returns, or both. According to Huang et al. and regulations, the national maize recommendation, and soybean and groundnut agronomic recommendations, which are referred to in the assessment. This would also provide useful feedback into the 2- In case of a fertilizer with higher analysis, the amount should be reduced proportionally. Winter and spring Forage Maize fertiliser recommendations and guidelines Developed from DEFRA RB209 8th Ed by Farming Online. The following table gives a general recommendation for fertilising maize with inorganic fertilisers: 3 Yield potential of maize Fertiliser Less than 3 to 5 t/ha 5 to 8 t/ha 8 to > 12 t/ha Type .
