TL;DR: A field experiment was conducted for two consecutive years (2007-09) with the objective to find out the best combination and type of organic and inorganic fertilizers for wheat (Triticum aestivum L.) production as discussed by the authors.
Abstract: Recently, the interest in organic farming is increasing among the researchers and farmers due to the advent of high yielding cultivars and escalating fertilizer prices. Application of different organic manures in combination with inorganic fertilizer to wheat crop might give a substitute under field condition. A field experiment was conducted for two consecutive years (2007-09) with the objective to find out the best combination and type of organic and inorganic fertilizers for wheat (Triticum aestivum L.) production. The experiment was laid out in randomized complete block design (RCBD) with three replications. The treatments were: control (T1, no manure), departmental recommendation 128+114+62 NPK Kg ha -1 (T2), farmyard manure @ 10 tons ha -1 at time of seed bed preparation (T3), poultry manure @ 6 tons ha -1 + 128-114-62 Kg ha -1 NPK (T4). At maturity, plant height (cm), spike length (cm), number of spikelets per spike and grain yield from 1m 2 area of randomly selected plants were recorded. Results led to the conclusion that T4 gave the best result with combination of 6 t/ha poultry manure + 128-114-62 kg ha NPK.

TL;DR: In this paper, an integrated nutrient management system is proposed for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting environment.
Abstract: Depletion of soil fertility is a main problem to sustain agricultural production and productivity in many countries. The use of inorganic or organic fertilizer alone has both positive and negative effects on plant growth, nutrient availa-bility and the soil. Organic fertilizer improves physical and biological activities of soil but they have comparatively low in nutrient content, so larger quantity is required for plant growth. However, inorganic fertilizer is usually immediately and fast containing all necessary nutrients that are directly accessible for plants. But continuous use of inorganic fertilizers alone causes soil organic matter: degradation, soil acidity and environmental pollution. So the integrated nutrient management system is an alternative system for the sustainable and cost-effective management of soil fertility by combined apply of inorganic with organic materials resulting in rising soil fertility and productivity without affecting environment. The objective of the present review is to assess the effect of mixing organic with inorganic fertilizer on soil fertility and productivity. The study revealed that appropriate application of organic with inorganic fertilizers increases the productivity without negative effect on yield quality and improves soil fertility than the values obtained by organic or inorganic fertilizers separately.

TL;DR: The objective of this review is to discuss the technological advances in engineering lignocellulosic biomass as an economically attractive feedstock and robust microbial platforms as a powerful biofuel producer.
Abstract: Lignocellulosic biofuel has been globally recognized as a renewable energy source with environmental benefits while minimizing the competition between food and fuel supply. Although lignocellulose is a promising renewable feedstock for the sustainable production of transportation fuels, cost-effective conversion technologies are necessary to overcome its inherent recalcitrance that impedes the widespread utilization of lignocellulosic biofuels. Owing to the limited availability of cost-effective and less recalcitrant biomass, the major challenge toward biofuel commercialization includes the biochemical and genetic modification of lignocellulose in energy crops. The development of robust microbial conversion systems capable of converting a broad spectrum of carbon sources derived from biomass feedstocks into a variety of biofuels such as bioethanol, biodiesel, and advanced drop-in biofuels is also of interest in the field of biorefinery. To date, metabolic engineering and synthetic biology have made significant advances in improving the biofuel yield in feedstocks and microbial engineering. The objective of this review is to discuss the technological advances in engineering lignocellulosic biomass as an economically attractive feedstock and robust microbial platforms as a powerful biofuel producer. Finally, integrating engineering strategies and efforts in plant and microbial engineering provides future directions of an interdisciplinary approach to facilitate the commercialization of economically feasible lignocellulosic biofuels.

Abstract: This study was conducted to evaluate the effect of liming (CaCO3 1000 kg ha−1) and application of organic fertilizers (rotted farmyard manure 40 t ha−1) and six different combination of mineral fertilizers: NPK 15:15:15 800 kg ha−1 + KAN (calcium ammonium nitrate) 240 kg ha−1; NPK 15:15:15 400 kg ha−1 + MCB (water-soluble mineral fertilizer NPK 13:11:20 + 2MgO + microelements + humic acid) 300 kg ha−1 + KAN 125 kg ha−1; MCB 400 kg ha−1; MCB 400 kg ha−1 + KMg (water-soluble mineral fertilizer Multi KMg 13:0:43 + 2MgO) 100 kg ha−1; MCB 600 kg ha−1 + KMg 100 kg ha−1 and MCB 800 kg ha−1 + KMg 100 kg ha−1 on yield and other productivity parameters of potato (Kennebec variety). The aim of the research was to optimize the system of potato plant nutrition for maximum profitability in the future potato production on acid soils of mountainous region of Montenegro. The experiments were carried out during 2015 and 2016, on Dystric Cambisols. The results obtained suggested that in both years, the highest values for all studied parameters were measured on plots with combined application of liming, organic and mineral fertilizers. In addition, a significant influence on the increase in the number of tubers per plant, the average tuber weight and the total yield was also demonstrated in all individual trials of potato nutrition, and the interaction of organic manure and mineral fertilizer. Fertilizing with rotted farmyard manure had significantly increased potato productivity, with the effect more pronounced in treatments with liming. The highest number of tubers (6.2 and 7.2), average tuber weight (93.5 g and 101.0 g) and yield (27.6 t ha−1 in 2015 and 34.8 t ha−1 in 2016, respectively) were obtained using combinations of MCB 800 kg ha−1 + KMg 100 kg ha−1 on variants fertilized with rotted farmyard manure and liming. This research is a valuable source of information for potato growers and scientists from this region as the results have shown how fertilization is raising productivity in this environment and its importance in the future potato growing on acid soils in mountainous regions of Montenegro and Western Balkans.

TL;DR: In this article , the role of biochar in improving nitrogen uptake and quality of wheat in a calcareous soil under integrated N management (90, 120, and 150 kg N ha-1) applied each from urea, farmyard manure (FYM) and poultry manure (PM) along with control) in 2 years field experiments.
Abstract: Crop quality and nutrient uptake are considerably influenced by fertilizers inputs and their application rate. Biochar (BC) improves nitrogen uptake and crop productivity. However, its interaction with synthetic and organic fertilizers in calcareous soil is not fully recognized. Therefore, we inspected the role of biochar (0, 10, 20, and 30 t ha–1) in improving N uptake and quality of wheat in a calcareous soil under integrated N management (90, 120, and 150 kg N ha–1) applied each from urea, farmyard manure (FYM) and poultry manure (PM) along with control) in 2 years field experiments. Application of 20 t BC along with 150 kg N ha–1 as poultry manure considerably improved wheat grain protein content (14.57%), grain (62.9%), straw (28.7%), and biological (38.4%) yield, grain, straw, and total N concentration by 14.6, 19.2, and 15.6% and their uptake by 84.6, 48.8, and 72.1%, respectively, over absolute control when averaged across the years. However, their impact was more pronounced in the 2nd year (2016–2017) after application compared to the 1st year (2015–2016). Therefore, for immediate crop benefits, it is recommended to use 20 t BC ha–1 once in 50 years for enhancing the nitrogen use efficiency of fertilizers and crop yield.

TL;DR: In this article, the ENVIRON-GRO computer model was used to analyze the impact of N and irrigation management effects on crop yield and N leaching in organic farms.
Abstract: Groundwater has become increasingly degraded by NO 3 , and this degradation has been partially attributed to the use of commercial inorganic N fertilizers. Conversion from conventional fertilizer management to organic farming has been proposed as a means to reduce groundwater degradation. Matching soil inorganic N supply with crop N requirement on a temporal basis is important to achieve high yield and low water degradation. Dynamics of N mineralization from two manures and N-uptake dynamics for two crops were derived from published data, and multi year simulations were done using the ENVIRON-GRO computer model, which accounts for N and irrigation management effects on crop yield and N leaching. The temporal N-mineralization and N-uptake curves did not match well. The potential N uptake for corn (Zea mays L.) exceeded the cumulative mineralized N during a significant period that would cause reduced yield. Wheat (Triticum aestivum L.) has a low and flat N-uptake peak, so that the cumulative mineralized N met N demand by wheat during the growing season. A crop with a very high maximum N-uptake rate, such as corn, would be difficult to fertilize with only organic N to meet peak demands without excessive N in the soil before and after crop growth. In order to satisfy crop N demand, a large amount of manure, which would leave much N or subsequent leaching, must be applied. It took two or more years after conversion to organic sources of N to reach maximum yield because of carryover of unmineralized manure and accumulation of mineralized N after crop uptake which was not completely leached during the winter. High initial applications to build up the organic pool followed by reduced inputs in subsequent years would be appropriate.
