Application of nano- and micro-sized particles of cattle manure on soybean growth

Abstract

Background: Cattle manure (CM) is the most common organic fertilizer used by farmers. However, its usually slow decomposition leads to the use of chemical fertilizers. Therefore, experiments on nano-and micro-sized particles of CM were conducted to evaluate the possibility of accelerating its decomposition in soil. Methods: The effects of a sole application of CM in different sizes (nano-, micro-, and natural-sized particles) in two ranges (5 and 20 Mg ha -1 ) and the combined application of CM and chemical fertilizers on the plant growth characteristics of soybean (cv. JS 335) were studied at Gorgan University. Nano-and micro-sized particles of CM were produced using a ball mill, and their half-life in soil was measured. Soil properties were measured before planting. Grain yield, 1000 grain weight, number of pods per plant, biological yield, plant height, and nutrient contents in plant shoot material were measured. Results:The results showed that the use of nano-sized particles of CM (nCM) caused a significant increase in yield and yield components. Increasing the amount of crushing resulted in an increased rate of CM mineralization and in proper nitration before the formation of nodes in the roots. A significantly higher yield was obtained with nCM than with chemical fertilizer, and due to the nCM particles' half-life in soil, the plants were allowed to absorb nutrients for a longer time period. Conclusion: The nCM has two major advantages over chemical fertilizers in that it does not release nutrients as quickly as chemical fertilizers and the loss of nutrients from soil is low.

Effect of Fertilization with Mineral NPK and Spraying with Nano NPK on Growth, Yield and Quality of Onion

“…These results were true in the first and second seasons. These results were in agreement with that found by Ni et al, (2009), Ekinci et al, (2014), Liu and Lal (2014), Aryanpour et al, (2017); Merghany et al, (2019) and Gosavi et al, (2017) who stated that the positive effect of foliar applied nitrogen, phosphorus, and potassium to sustain proper leaf nutrition as well as carbon balance, and improving photosynthetic capacity is well established.…”

Effect of Mineral (NPK) Rates and Injection with Nano NPK on Growth, Yield and Quality of Onion

“…While, the lowest values for this trait (9.056 and 8.873) were obtained from control treatment (without injection) in the first and second season, respectively. These results were in agreement with that found by Liu and Lal (2014); Aryanpour et al, (2017); Gosavi et al, (2017);and Merghany et al, (2019) who stated that the positive effect of foliar applied nitrogen, phosphorus, and potassium to sustain proper leaf nutrition as well as carbon balance, and improving photosynthetic capacity is well established.…”

Characterization and Impact of Cattle Manure Particle Size on Physical Properties of Sandy Soils

“…The CMS 3 has more ability for retention of such as P and K. The partition coefficient was 1.8 L/kg for P and 8.12 L/kg for K, indicated that K is more binding on such materials than N and P. The results indicated that optimum size of manure is 0.8-0.4 mm; it has maximum sorption of both K and P because of their high reactivity due to the large surface to volume ratio leading to improve efficiency of nutrient adsorption. These results were in agreement with (Aryanpour et al, 2017). The maximum sorption of N occurred on CMS 2.…”

“…Perhaps this was due to improving the nutrient availability, nutrient holding capacity of soils, microorganism activity which effect of plant growth in sandy soils (Masarirambi et al, 2010;Mahmoud et al, 2013;Wendimu, 2016). The increase in fresh weight, dry weight and number of leaf yield might be due to that cattle manure in small particle sizes has a less half-life in soil (Aryanpour et al, 2017).…”
