Abstract:
Apple cultivation in Japan typically involves the use of chemical fertilizers and pesticides which can damage the environment. Therefore, in this study we investigated the orchard soil biochemical characteristics as well as the fruit nutrient contents, and pesticide residues of apples grown either organically (organic fertilizers + reduced pesticides) or with conventional chemical fertilizers and pesticide rates. Compared with conventional chemical fertilizer treatment, the organic fertilizer treatment produced fruit with significantly higher contents of sugar, as well as soil with higher tota

A study to assess the effects of fertilizer application on either coconut or coffee or both, in an intercropping system was conducted from 1985 to 1991. at the Davao Research Center, Mindanao, Philippines. The coconuts were planted at 8 m x 8 m square system.
 
 Fertilizer application on coconut intercropped with either fertilized or unfertilized coffee increased copra yield significantly. A very slight increase in copra per nut was noted on un‑fertilized coconut even with fertilized coffee inter­crop indicating coconut did not benefit from the fertilizers applied on coffee. Bean yie

Abstract:
Intensification of horticulture in Russia involves planting of new high-density orchards with drip irrigation and fertigation as well as intensification of the exploitation of traditional orchards. This approach involves an increase in mineral fertilizer application imposing the risk of soil fertility loss. For several reasons, the use of traditional organic fertilizers like manure in orchards is currently marginal. Although bacteria-based biofertilizers cannot substitute mineral fertilizers completely, they can significantly reduce the need for mineral fertilizer application. The effect of mi

Significant yield differences did exist between the 60% consumption use (CU) irrigation level and the 90% and 120% CU irrigation levels.

Abstract:
In Mediterranean-type climates, topsoil frequently dries out during spring. Problems associated with reduced nutrient (P, K) availability in dry topsoil may be overcome by placing fertilisers deeper in the soil, where the soil is more likely to remain moist for longer periods as opposed to conventional fertiliser placement. Deep-P placement has resulted in significant yield improvements for lupin crops in Mediterranean environments because lupin crops generally require soil P supply during spring (throughout the flowering stage); in contrast, wheat yields have seldom improved with deep P place

Abstract:
Physical properties of commercial fertilizers play important role from precision application point of view. Granulometric evaluation is usually performed by sieve separation according ČSN 01 5030 standard. The main subject of this work is the presentation of separation results when vertical airflow is used with NPK 20-8-8 and Dolophos fertilizers. The sample was divided into 8 individual specimens of 0.5 kg weight that was measured repeatedly. Every class of the specimen was than sieved on the sieves with holes 2 mm, 3.5 mm, and 5 mm resulting four new subclasses characterized by the sieve mes

Abstract:
Experiments involving a winter wheat (Triticum aestivum L.) variety ‘Širvinta 1’ were conducted at the Experimental Station of the Aleksandras Stulginskis University during the period 2006–2009 in limnoglacional silty loam on morainne clay loam Cal(ca)ri-Endohypogleyic Luvisol. Winter crops were grown on the background of N150P90K90 mineral fertilization and were additionally foliar-fertilized with amide nitrogen fertilizer, containing different concentrations of amino acids (0.5 %–3.0 %), at a winter wheat booting, heading and milk maturity stages. Experimental evidence showed that solutions

Abstract:
The article presents the results of studies of the effect of the fertilizer application on the enzyme activity of the barley rhizosphere in the conditions of the southern forest steppe of Western Siberia. The activity of the catalase enzyme decreased under the application of the studied factors up to 15 %, in comparison to the control. Under the influence of mineral fertilizers, there was a tendency for the increase of urease activity up to 17 %, in comparison to the control. The changes in soil invertase activity under the influence of the studied factors were within the experimental error.
