“…However, the N stored in cabbage heads was less than in faba bean seeds, resulting in a significant proportion of accumulated N in crop residues left in the field after harvest. About 63% of this residual N will likely be mineralized over winter and potentially lost via leaching to groundwater (Katroschan et al, 2014). However, N released from crop residues can be utilized by growing winter cover crops, which could reduce N leaching (Tei et al, 2020).…”

Intercropping can improve yield and nitrogen use efficiency in organic vegetable production by pairing crops with complementary resource use. An intercrop field experiment was conducted to determine yield, root growth and nitrogen (N) dynamics using faba bean (Vicia faba L.) grown as a vegetable and pointed cabbage (Brassica oleracea var. capitata cv. conica). Both crops were grown in monocropping (MC) and intercropping systems (IC). Minirhizotrons were used to measure root growth. Yield of pointed cabbage per metre row was 28% higher under the IC system than under MC, whereas faba bean yield as fresh seeds did not differ. The land equivalent ratio was 1.06, showing that improved yield under IC resulted from efficient land resource use. Even though MC cabbage had the highest aboveground biomass, total N accumulation was higher under IC and MC faba bean systems. Both root frequency and intensity were greater under IC faba bean rows compared with MC faba bean because of the presence of cabbage roots in faba bean rows. Monocropped cabbage had the highest root intensity and the lowest amount of soil mineral N in the 0–1.5 m depth after harvest. Monocropped cabbage was efficient in assimilating N, whereas MC faba bean was efficient in exporting N as harvestable yield. The nitrogen use efficiency using the IC system (75%) was higher than growing faba bean (44%) and cabbage (65%) alone. Thus, faba bean as an intercrop in organic cabbage production systems improves land and N use efficiency by complementary root growth.

“…In previous articles, the variation of the inorganic N availability from commercial organic fertilizers of animal origin was explained by the incubation temperature [61], the immobilization of inorganic N in the presence of high inorganic N contents in the soil [62], or by soil texture effects [63]. On the contrary, the correlation analysis carried out in this work suggested that the main factors for the mineralization rate could be described by the C to N org ratio of the fertilizer.…”

The prediction of nitrogen (N) mineralization or immobilization in organic fertilizers is an important tool to optimize fertilizer use, especially in intensive agricultural systems. Our aim was to derive a model to predict the N mineralization/immobilization from readily available information on the properties of organic fertilizers in farming practice. On the basis of a literature review, a characterization of organic fertilizers was performed, revealing a large variance in fertilizer properties within the defined categories and subcategories. A partial linear model was derived and used for the prediction of N mineralization/immobilization based on the type of fertilizer and the carbon (C) to organic nitrogen (Norg) ratio. Depending on the previously defined category, a strong mineralization (e.g., plant- and animal-based commercial fertilizers) or a predominant immobilization (e.g., compost and slurries) was detected. For a total of seven main categories and their subcategories, individual models were developed. This work shows that the mineralization properties of organic fertilizers can be sufficiently predicted through a simple classification into a fertilizer category and through the C to Norg ratio.

“…Other available techniques for estimating NUE consider plant available nutrient converted to yield. Nitrogen use efficiency calculated from fresh matter yield per unit available N (above-ground total plant N + residual soil mineral N) showed 173.9 kg/kg in organically fertilized (lupine (Lupinus angustifolius L.) seedlings + seed meal) white cabbage grown in Ruthe (Germany) [67].…”

Connecting Bio-Priming Approach with Integrated Nutrient Management for Improved Nutrient Use Efficiency in Crop Species

The increasing demand for qualitative and varietal foods by the consumer society is a big concern for energy production, and utilization of that energy in a judicious manner for sustainable management of resources is a big challenge in the eminent future. Existing resources (land, water, fertilizer, etc.) and their socioeconomic aspects warrant the farming community to adopt alternative strategies aimed at enhancing the use efficiency of inputs and improve the environmental quality. The adaptability of microbes to thrive in different environments has prompted scientists to introduce microbial intervention in the agricultural processes. Bio-priming has the potential to fulfill many objectives of the modern production system with the use of beneficial microorganisms in an eco-friendly manner. Interestingly, it also plays a crucial role in enhancing the nutrient use efficiency of crops. There is rising evidence of a paradigm shift from the use of a single microbe to a consortium approach for efficient rhizosphere engineering in the context of sustainable agriculture. Our understanding of different signaling cascades, rhizosphere chemistry, and other mechanisms of plant–microbial interactions will frame suitable strategies to harness the best ecosystem services including improved resource use efficiency.
