Increasing doses of farmyard manure (FYM) or equivalent mineral NPK fertilizers and their combinations were analysed in a crop rotation with potato, maize and winter wheat with special regard to their long-term influence on soil fertility. The yield-increasing capacity of FYM doses was only 82%, as compared to the equivalent amount of mineral NPK. Fairly high N release (50.9 kg ha −1 ) could be observed on the unfertilized plots. Great differences in N utilization were recorded, depending on the form and dose of fertilizers. The average N utilization from FYM was only 29.3%, while that of the equivalent fertilizer application was 49.8%. The lowest soil reactions were observed without fertilization and at the highest NPK doses. Negative N balances generally resulted in low soil organic matter content. FYM and equivalent NPK fertilizers had a similar influence on the ammonium lactate (AL)-extractable K 2 O content of the soil, while an increase in the AL-P 2 O 5 content could be observed in the case of mineral fertilization.

The pineapple plant cultivar 'Vitória' is resistant to Fusarium and it presents similar characteristics to the cultivars 'Pérola' and 'Smoot Cayene'. However, the expansion of this new cultivar depends on the development of research on several aspects, among them, fertilization. In this context, the experiment was carried out with the objective of evaluating soil fertility, foliar macronutrient contents and productivity in 'Vitória' pineapple plant in function of nitrogen fertilization with urea and chicken manure. The experiment was conducted under randomized block design, with four replications. Treatments consisted of five doses of N, in two sources of organic fertilization (chicken manure ) and mineral (urea), totaling nine combinations generated through the Central Composite Matrix of Box: T1 , 44 and 2.91; T 2 , 152 and 0; T 3 , 0 and 10; T 4, 44 and 17.1; T 5 , 260 and 2.91; T6 , 152 and 10; T7 , 152 and 20; T8 , 304 and 10; and T9, 260 and 17.1 g plant-1. At 6 months after planting the chicken manure decreased H + A1, Mg and CEC levels, and at 23 months after planting increased soil P, SB e CEC levels.  In the two seasons, Urea has reduced pH and it reduced Mg, SB and CEC contents at six months after planting. Doses of urea between 10 and 12 g plant-1 are recommended in order to maximize the productivity of the pineapple plant.

Aims: To evaluate the possibility of allelopathic effects of the rotated crops on productivity, chemical composition, N utilization of wheat and soil fertility. Study Design: A split plot design with three replications was used. The main plots were assigned with three previous crops, The sub plots were assigned by three nitrogen fertilizer rates (0, 35 and 70 kg N fed-1). Place and Duration of Study: A field study was carried out at Sakha Agricultural Research Station farm, ARC, Kafr El-Sheikh governorate, Egypt, during two successive seasons of 2016/2017and 2017/2018 Methodology: The local wheat cultivar (Sids 12) was sown after three crops (fahl berseem) after rice, (Drawa) after rice and Fallow after rice as preceded crops. Results: The results showed that fahl berseem roots and residues in the clover (berseem)-wheat rotation secreted biologically active chemical compounds which have a positive effect on growth and development of wheat. The preceding clover (fahl berseem) wheat rotation appeared to be promising for wheat productivity, N, P, K concentrations, N-uptake, N utilization, protein content of wheat grain and straw, availability of N, P and K after wheat harvest compared with fallow after rice, green maize (drawa-wheat rotation). The interaction between the preceded crops and N fertilizer rates was significantly for all the studied traits. The highest performance of wheat traits were observed when wheat was grown after fahl berseem and fertilized with 70 kg N.fed-1. While the lowest performance was obtained following cereal crops rice (fallow) and the lowest N level in both seasons. Treatment of fahl berseem with nitrogen fertilizer (70 kg N.fed-1) had given a best values from grain yield with relative increments of (37.54%) compared with preceding rice-wheat rotation and (23.26%) compared with rice-drawa rotation. Conclusions: Cereal winter crops can be sow after preceding legume crops rather than summer cereal crops. We can sow fahl berseem crop as a forage to animals after cereal crop (rice) and before sowing wheat crop to improve soil properties and its availability of the essential elements and consider additional revenue to farmer. Fahl barseem had be sown in the end of august month after rice crop to produce approximetly 20 ton fresh forage.fed-1 (~ 9 ton dry grass.fed-1) which provides farmers with (~ 9 thousands EL) in 88 days only.

The cupuassu (Theobroma grandiflorum (Willd. Ex Spreng.) K. Schum.) is a native fruit tree which has, in the past years, acquired great social and economic importance for the regional farmers. The nutrient-rich and often wasted cupuassu tree fruit shell residues can contribute to the improvement of the low fertility soil of Amazonia. A trial was carried out on a small holder’s cupuassu plantation in Central Amazonia to ascertain the effect of organic fertilization on the recovery of soil fertility and plant nutrition by using material from cupuassu shell residues and Inga edulis pruning (branches and leaves). The fertilization with cupuassu rinds + Inga prunings improved soil fertility, mainly by the increase of K and Ca in the soil, but only with liming, which appears to favor the mineralization of these nutrients. At the 0–10 cm depth, the Ca level increased about 50% compared to the control and the K level increased 75% compared to the cupuassu shell treatments. The significant increase of about 30% in N absorption by trees in the plots without liming shows that the application of green manure can increase the mineralization of N in Oxisols. These results show that the organic residue sources used can result in a nutrient-bearing organic fertilizer and become a low-cost alternative for recycling cupuassu processing residues.

SUMMARYA comparative study of the effect of organic fertilization at different times and doses on soil fertility and crop yield was performed over 3 years in a calcareous loamy soil. Nutrient availability in the soil and macronutrient concentration in leaves and in the edible part of the plants was examined in plots that were previously handled conventionally and ecologically for several years. The organic fertilizers used were manure compost at two doses in plots after 4 years of organic management treatment, and green residues of previous crops in plots with 10 years of organic management. In general, soil organic carbon (C), nitrogen (N), phosphorous (P) and magnesium (Mg) contents were found to be considerably greater in organically fertilized soils in comparison with soil receiving mineral fertilizer (conventional treatment (CT)). For C and N, the highest contents were observed in the long-term organic treatment (OR). However, few differences were found for potassium (K) and sodium (Na). The results obtained for electrical conductivity and pH indicated that, in general, there were no significant differences between treatments. The differences in the values of EC and pH occurred among cultivation cycles irrespective of the type of fertilization, but there was a contradictory trend for each of the above parameters. The results obtained for leaves and the edible part of the plant indicated that, in general, there were no significant differences between treatments, except for P with a trend for higher P content in organic crops. The nitrate values in leaves showed great variability, making it difficult to draw conclusions. The associations of fertilization and the chemical properties of soil with nutrient content in crops were checked by principal component analysis (PCA). For soil data, different clusters were observed between CT and OR treatments. However, PCA showed that the influence of crop type on plant nutrient concentrations was greater than type of fertilization. The effect of fertilization on crop yield was variable depending on plant species. The results indicated that organic fertilization did not cause deficiencies in the nutrient content and yield of vegetables when compared with conventional fertilization, showing that ecological management can be used effectively.
