Controlled-release fertilizers (CRF) are the newest and most technically advanced way of supplying mineral nutrients to nursery crops. Compared to conventional fertilizers, their gradual pattern of nutrient release better meets plant needs, minimizes leaching, and therefore improves fertilizer use efficiency. In our review of the literature, we found many terms used interchangeably with control...

Excessive nitrogen and insufficient calcium could significantly impact peanut yields. This study investigated the effects of fertilizers on nutrient absorption, utilization, yield; experiments were conducted using cultivar from Xianghua 2008 in a split-plot arrangement with two fertilizer levels (Ca0: 0 Ca1: 568 kg CaO ha−1) main plots six gradients (N0: 0, N45.0: 45.0, N90.0: 90.0, N112.5: 112...

High-precision oxygen isotope analyses were carried out on dissolved phosphate extracted from discharge waters from three wastewater treatment plants (WTP) located in western France, as well as on the different phosphate-based fertilizers applied by farmers in the same region. Measured delta(18)O values of phosphate from chemical fertilizers range from 19.6 to 23.1 per thousand, while those of ...

Soil-borne diseases caused by pathogenic microorganisms are one of the main factors responsible for the decline in crop yields in farmlands. Pathogenic Fusarium oxysporum causes serious damage to various crops, and, thus, a feasible diagnostic method for soil-borne diseases is required. We herein examined a simple method to evaluate the suppressiveness of soil microorganisms against a pathogen ...

Potassium is among the three essential macronutrients for tea plants, along with nitrogen and phosphorous, plays important roles in growth stress response. absorbed by plants larger amounts than any other mineral element except and, some cases, calcium. At present, more 59% of China’s gardens are a state potassium deficiency, which negatively affects quality yield. This paper reviews effects de...

This study was conducted to evaluate the effect of liming (CaCO3 1000 kg ha−1) and application organic fertilizers (rotted farmyard manure 40 t six different combination mineral fertilizers: NPK 15:15:15 800 ha−1 + KAN (calcium ammonium nitrate) 240 ha−1; 400 MCB (water-soluble fertilizer 13:11:20 2MgO microelements humic acid) 300 125 KMg Multi 13:0:43 2MgO) 100 600 on yield other productivity...

Citrus are one of the most important fruit crops in world, and citrus hybrid cv. Beni-Madonna (BM) is widely cultivated Xiangshan County China because its profitability. However, due to lack technical guidance management, nutritional unbalances trees occur frequently a major constraint for quality yield. In this study, soil status 62 orchards three diverse landforms (mountain, flat, coastal sal...

The excessive use of chemical fertilizers can lead to severe environmental damages. In recent decades, the application biostimulants improve soil composition and stimulate plant growth has contributed significantly preservation. this paper, we studied effect a rhizogenic biostimulant, obtained from fulvic acids, probiotics, prebiotics, on fertility two types soils, sandy loam in which turfgrass...

In semi-arid tropics, sugarcane yield and quality are affected by deficiencies in soil nutrients, including potassium calcium. We examined the effects of two different fertilizers, a traditional muriate potash (MOP) polyhalite (which contains calcium), on growth, yield, quality. Experimental treatments compared control 0 kg K ha?1 (T1) to applied as MOP only at 80 (T2) 120 (T3), an equal split ...
