Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; 0.10-0.20; and 0.20-0.40 m in depth were collected and analyzed in the second year of an experiment installed in 2006 in a Rhodic Hapludox under no-till farming, located in ...

The effect of sewage sludge fertilization on nitrogen and sulphur content in maize was assessed in a pot experiment conducted in 2003-2005. The experimental design comprised the following treatments in four replications on three soils: treatment without fertilizer – (0); mineral fertilization – (NPK); farmyard manure – (FYM); sewage sludge A – (SSA); a mixture of sewage sludge A with peat – (MS...

MOJ Food process Technol 2017, 4(4): 00101 wheat as basic food regarding both its organic and inorganic macroand micro components [2]. This consideration is the result of several factors among which the increase of analytical possibilities has to be emphasized in addition to factors related to production technology that often change (cultivars, hybrids, crop protection, fertilization, frequency...

This paper presents the effect of soil supplementation with urea and magnesium on nitrogen uptake and its utilization by two different types of hybrid maize cultivars. Based on the results of 3-year fertilization studies, it was shown that for average volume of grain yield of maize, nitrogen content in grain dry matter and nitrogen uptake with its yield was significantly determined by the doses...

The objective of this work was to evaluate the effects of potassium (K) fertilization on vegetative growth, fruit production and leaf mineral content of olive tree (Olea europeae L.) under rainfed condition. Different fertilizer, techniques and rates of application were applied in 2003 on Chemlali olive. The potassium fertilizer used was potassium nitrate. The foliar fertilizer rates were 50 an...

Net N mineralization rate (NMR), net N consumption rate (NCR), microbial biomass carbon (MBC) and nitrogen (MBN), potentially mineralizable N (PMN) and mineral N (N-NH4 + and N-NO3 –) were measured in paddy soil at five growth stages of rice to determine the effect of long-term fertilization in subtropical China. The studied long-term treatments included CK (no fertilization), N, NP, NPK and NP...

The pine nut from the stone pine (Pinus pinea L.) is the most important edible fruit in mediterranean forests. Despite this fact, there is a lack of knowledge regarding the application of agronomy techniques in stands of this species to increase pine nut production. Our study focuses on the effect of mineral fertilization on cone production and size, which in turn, are closely related to nut yi...

This study aimed to demonstrate the impact of phosphorus (P) mineral fertilization on topsoil P content and P leaching. We evaluated 83 datasets from 25 years from lysimeter experiments involving different cropping systems (winter crop, summer crop and autumn tillage, harvested grass) or unfertilized fallow, four types of soil texture, and three levels of applied mineral P fertilizer. A positiv...

The aim of this study was to determine the effect of mineral fertilization on the activity of alkaline and acid phosphatase and content of available phosphorus in soil under winter wheat cultivation. The fi rst factor of experiment was the fertilization with P, K, Mg, Ca and S in six levels: 1 (P, K, Mg, Ca and S), 2 (K, Mg, Ca and S), 3 (P, Mg, Ca and S), 4 (P, K, Ca and S), 5 (P, K, Mg, Ca), ...
