Sandy-textured soil infertility poses a problem for sustainable crop cultivation. This problem is usually dealt with by the addition of chemical fertilizers, which are expensive and can cause serious environmental issues if not managed well. A better alternative to improve and manage sandy soil infertility is the use of organic amendments produced from agro-wastes. This two (2)-year field study was conducted in a sandy-textured soil grown with black pepper to evaluate mainly the effects of chemical fertilizer, fermented plant and fruit juices, compost, and biochar on soil properties and morpho-physiological characteristics and yield of black pepper. Generally, the results indicated that the combination of fermented fruit juice, compost, and biochar was comparable to and in some cases better than chemical fertilizer in terms of soil physical, chemical, and biological properties as well as crop performance. These findings were even more pronounced in the second year of measurements. There were strong positive relationships between soil N and pepper leaf chlorophyll content and between soil microbes and soil respiration. The findings showed that these soil amendments produced from agro-wastes are a good alternative to the use of chemical fertilizers on sandy soils to improve soil fertility and productivity and the yield of black pepper sustainably.

Microbiological Indicators

Soil is a non-renewable natural resource, considered as the basis for food production. Changes in soil properties may indicate potentially beneficial or degradative effects of a given management practice, so it is important to select the most sensitive soil properties to act as quality indicators. This research evaluated different approaches to selecting soil quality indicators in the construction of soil quality indices (SQIs). The sensitivity of integrative SQIs, constructed by considering diverse chemical, physical, and biological properties, was compared with biological SQIs, using only biochemical and microbiological indicators, to assess soil quality in an intensive horticultural production system under short- and long-term organic and conventional management. The results provided by the SQIs showed that plots under organic management had increase soil quality compared with the conventionally managed plots, independent of the number of years under production. The SQIs integrated by physical, chemical and biological indicators were more sensitive than indices composed only of biological indicators, as they did not reflect the physical properties of the studied plots. The organic amendments had a great influence on the microbial community; therefore, microbiological indices could not provide reliable information on soil quality in production systems with high inputs of organic materials.

Desert soil is one of the most severe conditions which negatively affect the environment and crop growth production in arid land. The application of organic amendments with inorganic fertilizers is an economically viable and environmentally comprehensive method to develop sustainable agriculture. The aim of this study was to assess whether milk tea waste (TW) amendment combined with chemical fertilizer (F) application can be used to improve the biochemical properties of sandy soil and wheat growth. The treatments included control without amendment (T1), chemical fertilizers (T2), TW 2.5% + F (T3), TW 5% + F (T4) and TW 10% + F (T5). The results showed that the highest chlorophyll (a and b) and carotenoids, shoot and root dry biomass, and leaf area index (LAI) were significantly (p < 0.05) improved with all amendment treatments. However, the highest root total length, root surface area, root volume and diameter were recorded for T4 among all treatments. The greater uptake of N, P, and K contents for T4 increased for the shoot by 68.9, 58.3, and 57.1%, and for the root by 65.7, 34.3, and 47.4% compared to the control, respectively. Compared with the control, T5 treatment decreased the soil pH significantly (p < 0.05) and increased soil enzyme activities such as urease (95.2%), β-glucosidase (81.6%) and dehydrogenase (97.2%), followed by T4, T3, and T2. Our findings suggested that the integrated use of milk tea waste and chemical fertilizers is a suitable amendment method for improving the growth and soil fertility status of sandy soils.

A field experiment was conducted on Sawargaon series of isohyperthermic family of Vertic haplustepts to study the effect of application of primary treated biomethanated spentwash (PBSW) through irrigation on soil properties, nutrient uptake and yield of soybean – wheat cropping sequence. The bulk density and hydraulic conductivity of soil were improved in 100% recommended dose (RD) of N through PBSW with and without P chemical fertilizer at soil depths of 0-15 and 15-30 cm. The lowest soil pH, calcium carbonate and highest electrical conductivity, organic carbon, available K, exchangeable sodium (Na), exchangeable sodium percentage (ESP), cation exchange capacity (CEC), sodium adsorption ratio (SAR) and pooled bacterial, fungal and actinomycetes populations in surface (0-15 cm) soil depth were observed in 100% RD of N through PBSW + with and without P chemical fertilizer at all three soil depths (0-15, 15-30 and 30-60 cm) over the other treatments. The highest pooled available soil P was recorded in 50% RD of N through PBSW application through irrigation and remaining N and P through chemical fertilizers in all three soil depths. The significantly highest total NPK uptake by cropping sequence and highest mean Benefit : Cost (B:C) ratio of soybean and wheat was recorded in 25 % RD of N through PBSW + remaining N and P through chemical fertilizers over the rest of the treatments. The 25 % N-recommended dose of soybean and wheat crop can be replaced by application of PBSW through irrigation in sequence without disturbing soils by salt load.

Compost is considered to be superior fertilizer for soil quality and productivity, and is commonly used with chemical fertilizer. The optimal mixed ratio of compost with chemical fertilizer and the best application time is necessary to know for sustainable agriculture practices and management. Compared to the control treatment, this study comprehensively evaluated the effects of four mixed ratios of compost with chemical fertilizer, two nitrogen application times of chemical fertilizer, and their interaction on the soil properties, plant traits, yield, and quality of tomato plants. The soil properties, plant traits, and yield of tomato with all compost-mixed fertilizers performed better than the treatment without fertilizer. Furthermore, the amounts of available nitrogen, phosphorus, organic matter, plant weight, and yield in a 30% chemical fertilizer + 70% compost treatments (CF30) were even better than those with pure chemical fertilizer (CF100). No significant effect of nitrogen application time and its interaction with the mixed ratio treatment was detected, and the quality of fruit remained consistent among treatments. This study demonstrated a suitable practical application method for cow manure compost as a nutrient source in tomato crop production under silty loam soil.

A field experiment was conducted at the field laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh to evaluate the effect of molybdenum (Mo) with recommenced chemical fertilizer and organic matter on yield and quality of rice cv. BRRI dhan 30. Three levels of Mo viz. 0, 100 and 200 ppm were applied with recommended dose of chemical fertilizers (80, 15, 40, 10, 1.5 kg ha-1NPKSZn) and organic matter as both cow dung and compost. Plant height, number of ear bearing tillers hill-1, straw yield and biological yield were maximum when 100 ppm Mo was applied with chemical fertilizer. Number of total spikelets panicle-1, grains panicle-1, nitrogen content, nitrogen uptake in grain and straw, and protein content in grain were recorded better when 100 ppm Mo was applied with cowdung. Those parameters were minimum when 0 ppm Mo was applied with either cowdung or compost or NPK. The best performance was obtained when 100 ppm Mo was applied either with recommended fertilizers or with cow dung/compost. The performance of rice with 200 ppm of Mo was better than no addition of Mo in respect of yield and yield contributing characters.

The last nutrient management review of black pepper was done in 1968. There is, therefore, a need to develop new technology to improve pepper production and transfer that technology to production site. This experiment was carried out to study the effect of newly developed biochemical fertilizer on some physiological characteristics, yield and soil fertility of pepper. The treatment consisted of T1 (BS): chemical fertilizer (N:12%, P:12%, K:17%); T2 (BK1): biochemical fertilizer F1 N:15%, P:5%, K:14) and T3 (BK2): biochemical fertilizer F2 (N:13%, P:4%, K:12). The biochemical fertilizer F1 out-yielded chemical and biochemical fertilizer F2 by 75.38% and 16.45% respectively with the higher yield being associated with various phonotypical alterations, which are reported here. Significant measureable changes were observed in physiological processes and plant characteristics, such as large leaf area index, more chlorophyll content and high photosynthesis rate coupled with lower transpiration rate in biochemical fertilizer F1(BK1) treatment compared with other treatment. The high fertility level in biochemical fertilizer F1 and biochemical fertilizer F2 (BK2) reflected the important of organic material in improving soil quality. In conclusion, the achieve high growth performance and yield in pepper, chemical fertilizer alone is insufficient whilst combination of organic and inorganic fertilizer with balance nutrient content gave a significant increase in yield and growth of pepper.
