“…This might be because of legumes have capability to fix atmospheric-N through symbiosis (Table 1). It was agreed with works of [23] that reports, cereal-legumes intercropping patterns' effect on total soil N as significant. Likewise, [17] reports legume is grown in a mixture with a cereal, it can improve the N economy of the cereals both by contributing N to the soil for uptake by the cereal or simply by the legume removing less N than if the cereal was grown as a pure stand.…”

Mono cropping is the dominant factor influencing plant nutrient uptake and loss of soil quality in Ethiopia whereas intercropping of cereal/legume has positive environmental qualities. Likewise drought and moisture stress condition is widely expanding from all direction to the center of the country. Therefore, the objective of this research was to evaluate influence of planting methods, tied ridge and cropping system on different soil chemical properties in case of Madda Walabu district, Southeast Ethiopia. It was undertaken at Bidire from March 2016 to January, 2017. In this experiment, one maize variety (Melkassa 2) and one haricot bean variety (Nasir) were used. Treatments include open end and closed end tied ridge; sole cropping and intercropping; and in furrow, on ridge and flat bed planting. Each treatment has been triplicate and the experiment plots were laid out in randomized complete block design. Intercropping of maize-haricot bean with tied ridge and planting methods were highly influenced soil pH, exchangeable potassium, available phosphorous, soil organic matter and total soil nitrogen. Generally, the use of intercropping and closed end tied ridge in combination with in furrow planting significantly increased (p 0.05 ) soil fertility in the system, which could be promising for sustainable improvement of crop production and productivity for semi arid areas of Bale zone.

“…Contrary to our results, the change of bacterial community structure by fertilizer had been observed in several long-term field experiments (Sun et al, 2004;Hatch et al, 2007). Similarly, in Ahmad et al (2014), fertilizer treatments significantly (P < 0.01) increased microbial biomass nitrogen (MBN) and microbial biomass carbon (MBC) with the maximum increase in mixed application of farmyard manure and mineral fertilizers treatment, both in surface and sub-surface soil. The addition of organic and inorganic fertilizers in an integrated form increased soil organic matter content that provides a carbon source and other nutrients for microbes (Courtney & Mullen, 2008) and altered the biochemical properties of the soil by increasing potentially mineralizable N and microbial biomass C and N (Monaco et al, 2008).…”

The present study was carried out to investigate the influence of crop rotation and fertilization on the number of different groups of microorganisms. Soil samples were taken from the following treatments: 1. Monoculture of maize, 2. Maize-wheat (without fertilization), 3. Maize-wheat (with fertilization), 4. Maize-soybean-wheat (with fertilization), 5. Pasture soil, 6. Forest soil under oak, from three depths: 0-10 cm, 10-20 cm, and 20-30 cm in May and October 2012. Microbiological analyses included the determination of total number of bacteria, number of fungi, actinomycetes, aminoheterotrophs, and azotobacter. The number of investigated groups of microorganisms was higher in May on average. Fertilization did not affect the number of investigated groups of microorganisms. Crop rotation positively affected the total number of bacteria and the number of aminoheterotrophs in soil under maize.

“…About a half of China's maize production and a third of its soybean production come from the highly productive Black Soil in NE China (Duan et al 2011;Liu et al 2011). Maize-maize-soybean rotation increased organic nitrogen content in soil with the same fertilization compared with continuous cultivation of maize, which corroborates with previous findings from various rotation studies (Al-Kaisi et al 2005;Ahmad et al 2014). However, the area for crop rotation has shrunk in recent years in NE China due to the higher maize price and lower soybean price in the market, which has been replaced by a continuous cultivation of maize, consequently resulting in soil fertility decline.…”

Yan L., Li H., Zhang J., Zhang Z., Zhu P., Gao Q., Lu W. A long-term (18 years) effect of different fertilization and tillage management practices-fallowing treatment (no fertilizer, no cultivation); CK (no fertilizer, cultivation); N (nitrogen fertilizer); NP (nitrogen and phosphorus fertilizer); NK (nitrogen and potassium fertilizer); PK (phosphorus and potassium fertilizer); NPK (nitrogen, phosphorus, and potassium fertilizer); M1NPK (chemical fertilizer plus manure); 1.5M1NPK (1.5 times M1NPK); NPKS (mineral fertilizer plus straw); Rot (3-year crop rotation of maize-maize-soybean with M1NPK), and M2NPK (2 times manure plus mineral fertilizer) -on the content of total nitrogen and organic forms of nitrogen and the nitrogen content in different particle-size fractions were studied in topsoil (0-20 cm) in Black Soil of NE China by using the methods of Bremner. The results showed that the combined application of organic and mineral fertilizers could significantly increase the contents and proportions of total nitrogen and organic nitrogen forms in soil. Comparing to CK treatment, the content of total nitrogen and hydrolyzable nitrogen increased in the fallow and organic materials treatments. Compared with M1NPK treatment, rotation was more beneficial to increasing organic nitrogen content, especially remarkably increasing amino acid nitrogen. The nitrogen response of sand, silt, and clay was most sensitive on manure; the effects of fallow and manure treatments on sand were notable, the nitrogen content in sand with NPKS increased by 40.86% compared with CK treatment. Our results imply that fallow/rotation managements, and manure/straw application can improve soil fertility.
