“…Furthermore, no correlation between the investigated parameters and the P uptake of catch crops was found. The positive effect of plant residues on soil nutrient content was also found by Cavigelli and Thien (2003) and Reddy, Subba, and Singh (2005).…”

The efficient use of phosphorus (P) is a main task in sustainable agriculture. In pot and field experiments, the effects of green fertilization with catch crops and P supply with organic and inorganic fertilizers on plant and soil parameters were investigated on a P-poor loamy sand. For the field experiment, the catch crops were sown in September and remained on the plots until next spring. As the main crops, oilseed rape (Brassica napus), spring barley (Hordeum vulgare), and spring wheat (Triticum aestivum) were cultivated. The yield and P uptake of the main crops were determined. In the soil, the organic matter content, pH, P in soil solution (Psol), double-lactate and oxalate P content, P sorption capacity, and degree of P saturation were measured. Soil from plots of selected fertilizer treatments of the field experiment [without P, cattle manure, compost, triple-super P, green fertilization with Phacelila (Phacelia tanacetifolia)] was used for the pot experiment. Maize (Zea mays), ryegrass (Lolium westerwoldicum), and buckwheat (Fagopyrum esculentum) were cultivated for 3 months in pots with 6 kg soil. All applied forms of fertilizer affected the P contents in soil and the yields and P uptakes of main crops in both experiments. For green fertilization especially, phacelia was found to contribute to the P supply of the main crops, because it increased the P uptake as well as the readily available P contents in soil significantly. The cultivation of ryegrass led to a reduction of the P availability in soil. The DPS was also affected due to the catch crops. In average of the three years of the field experiment the DPS was 47.0% when phacelia was cultivated and 44.5% when ryegrass was cultivated. A better P availability and P utilization by catch cropping can help to reduce the need for external P input.

“…Use of organic materials including crop residues, manures, composts and other rural and urban biogenic waste has been suggested to enhance soil nutrient bioavailability and to increase fertiliser use efficiency (Gichangi et al, 2009;Takeda et al, 2009). However, the effect of the organic amendments on nutrient availability depends on their decomposability and nutrient concentration (Singh and Jones, 1976;Reddy et al, 2005).…”

A 72-day greenhouse pot experiment was conducted with a sandy loam or a silt loam soil to examine the effects of farmyard manure (FYM), poultry litter (PL) and biogenic waste compost (BWC) at 10 g dw kg -1 soil on microbial biomass and activity and growth and nutrient uptake by wheat. Soil samples were collected at days 0, 14, 28, 42, 56 and 72 after planting. Growth and nutrient uptake by wheat were determined on day 72. All three amendments increased microbial biomass C, N and P, dehydrogenase activity, plant growth and nutrient uptake with a greater effect by FYM and PL than by BWC. All amendments increased microbial biomass C, N and P and enzyme activity particularly on day 0. These microbial parameters decreased after day 0 indicating microbial biomass turnover. All amendments increased plant growth and nutrient uptake. It is concluded that organicamendments can stimulate microbial growth and nutrient uptake as well as plant growth and nutrient uptake. Microbes can increase plant nutrient availability by nutrient mobilisation but also because nutrients taken up by the microbial biomass initially could become available to plants when the microbial biomass turns over as the easily available C is depleted.

“…Manure, mulches, cover crops and composts have been used effectively for supporting rapid cycling of soil nutrients through microbial activity and supplying nutrients to different crops (Trujillo, 2002). However, nutrient availability from these organic amendments depends on their decomposition rate and nutrient concentration (Reddy et al, 2005). The benefits of these organic soil amendments are, however, often short-lived, since decomposition rates are very high and the added organic amendment is usually mineralized to carbon dioxide (Mekuria and Noble, 2013).…”

In a field trial, Dalbergia sissoo biochar was used to investigate its potential for improving growth, yield and nutrient recovery of wheat (Triticum aestivum L.), at varying fertilizer rates under calcareous soil. Two biochar levels (0.0 and 1.0% of soil weight) were used along with five fertilizer rates i.e. 0, 25, 50, 75 and 100% of recommended inorganic fertilizer dose (RFD). Seeds of wheat cultivar Faisalabad-2008 were sown in the field using 2 factorial-randomized complete block design. At reduced fertilizer rates, biochar application improved plant growth parameters i.e. plant height, spike length, number of tillers hill −1 and grain yield over the respective treatments having inorganic fertilizer without biochar. Regarding nitrogen (N), phosphorus (P) and potassium (K) content, the highest statistical results were achieved at reduced fertilizer doses along with biochar application i.e. N and P content in wheat straw and grain at 50% RFD, straw N and P uptake at 75% RFD, grain N and K uptake at 50% RFD and grain P uptake at 75% RFD. The highest N, P and K recovery was calculated in the treatments having 50% RFD + biochar with 95%, 25% RFD + biochar with 38% and 25% RFD with 117%, respectively. In comparison with control treatment (without fertilizer and biochar), biochar application improved soil CEC up to 40%. With biochar application, no any significant change was observed in other soil chemical properties i.e. pH and EC. The results suggested that 1.0% biochar along with reduced fertilizer doses, could be effectively used to improve wheat growth, yield, nutrient content and nutrient uptake under field condition. Moreover, 1.0% biochar along with 75% of RFD can be effectively used in place of 100% RFD to get the highest yield.
