“…On the other hand, a slight increase was observed on the mean value of soil pH as indicated in Table 2 under all agricultural practices with soil depth. As indicated by Foth and Ellis [12], the current soil pH values observed in the study area were within the range of moderate acidic soil. Numerous scholars [13,14,15,16] reported that soil pH was lower in agricultural than grazing land; this might be due to the depletion of organic matter because of intensive agriculture practices and also due to the highest microbial oxidation that produces organic acids, which provide H ions to the soil solution.…”

Conservation agriculture is claimed to be one of the solutions for the problems of poor agricultural productivity in sub-Saharan countries. The impact of conservation agriculture depends on environmental factors such as slope, vegetation, soil type, rain fall pattern and intended crops. This study was conducted from 2013 to 2014 with the objective of assessing the impact of conservation agriculture practices on soil chemical properties. Five main treatments were selected for the study: Monocropping (maize) without crop residue, Monocropping (maize) with crop residue, Crop rotation (maize and haricot bean) with crop residue, Intercropping (Haricot bean with maize) with crop residue and a grazing land as a control. A Randomized complete block design with four replications was used. A total of 40 composite soil samples (4 replication * 5 treatments * 2 soil depth) were collected and analysed for selected soil chemical properties. Results showed that soils in the study area were moderately acidic, and contained medium level of available phosphorus (AP) (7.33±0.58

“…Phosphorus is known as the master key nutrients to agriculture because lack of available Phosphorus in the soils limits the growth of both cultivated and uncultivated plants (Foth and Ellis 1997). Phosphorus is in agriculture field are added second to nitrogen in frequency of use as fertilizer nutrient (Trohel and Thompson 1993).The residual accumulation of phosphate ion due to long-term use of inorganic phosphate fertilizer and its high fixation affinity might be the cause of high amounts of available phosphorus in the majority sites.…”

Soil fertility assessment is a key for sustainable planning of a particular area. Thus, the present study was conducted to assess the soil fertility status of the Regional Agricultural Research Station, Parwanipur, Bara, Nepal. The study area is situated at the latitude 27°4’40.9’’N and longitude 84°56’9.85”E at 75masl altitude. Altogether 76 soil samples were collected based on the variability of land at 0-20 cm depth. The texture, pH, OM, total N, available P2O5, K2O, Ca, Mg, S, B, Fe, Zn, Cu and Mn content in the samples were determined following standard analytical methods. Arc-GIS 10.1 was used for soil fertility mapping. The soil structure was angular blocky, and varied between grayish brown (10YR 5/2) and dark grayish brown (10YR 4/2) in color. The sand, silt and clay content were 24.41±0.59%, 54.57±0.44% and 21.03±0.32%, respectively and categorized as silt loam and loam in texture. The soil was moderately acidic in pH (5.67±0.09), low in organic matter (0.74±0.04%) and available Sulphur (0.8± 0.1 ppm). The total nitrogen (0.06±0.001%), available boron (0.59±0.08ppm) and available zinc (0.51±0.05ppm) were low. Furthermore, available potassium (50.26±2.95ppm), available calcium (1674.6±46.3ppm) and available magnesium (175.43± 8.93ppm) were medium. Moreover, available copper (1.36±0.06 ppm) and available manganese (16.52±1.12 ppm) were high, while, available phosphorus (77.55±6.65 ppm) and available iron (85.88±7.05 ppm) were found high. It is expected that the present study would help to guide practices required for sustainable soil fertility management and developing future agricultural research strategy in the farm.

“…Apart from direct damage to the plants, low temperature also reduces the diffusion coefficient of nutrients (Foth & Ellis, 1996), which for immobile nutrients like P is of major importance. Hund, Richner, Soldati, Fracheboud, and Stamp (2007) showed that a high density of lateral roots can improve early vigour of young seedlings under chilling stress conditions, presumably because it helps alleviate reduced P availability.…”

“…Low temperature may hamper seed germination and seedling growth and affects shoot and root development, root branching and elongation (Cutforth, Shaykewich, & Cho, 1986;Parera & Cantliffe, 1994). Low temperature also reduces nutrient diffusion (Foth & Ellis, 1996) and solubility, and thus availability in soils, consequently decreasing plant nutrient uptake (Pregitzer & King, 2005). Several strategies have been proposed to alleviate the symptoms of cold stress in crops.…”

Maize is becoming an increasingly important crop in northern Europe, but low temperatures during spring may hamper its growth. This effect may be caused by direct plant damage through oxidative stress or indirect damage through decreased uptake of nutrients, especially phosphorus (P), from the soil. Previous studies have indicated that treatment with micronutrients such as manganese and zinc (Mn/Zn), microbial inoculants (biostimulants) or exogenous salicylic acid can alleviate abiotic stress. Seed inoculation with microorganisms can also increase P uptake from the soil. In a pot experiment, we investigated whether the negative effects of cold stress could be alleviated by improving soil fertility (P level), inoculating seed with two different plant growth‐promoting fungi of the genus Penicillium sp., adding extra Mn/Zn at sowing or adding exogenous salicylic acid. These treatments were tested on maize plants subjected to cold stress and two different levels of soil fertility and harvested 28 and 51 days after sowing (DAS). We found that the effect of cold stress was not alleviated by improving soil fertility through the use of a more fertile (high P) soil or through fertilisation with plant‐available P in the form of triple superphosphate. Cold stress was also not alleviated by the treatment of seeds with salicylic acid. Addition of Mn/Zn and inoculation with one of the two Penicillium strains tested increased biomass production at 51 DAS (compared with the untreated control) in cold‐stressed plants grown in the high P soil, but not in the low P soil. Thus, addition of Mn/Zn and inoculation with Penicillium sp. can reduce the effects of cold stress in maize plants grown in fertile soil.
