Available nutrient status and their correlation with the physico-chemical properties is an important indicator of soil health and plant nutrition. To comprehend the nutrient status in relation to soil properties in apple orchards a study was conducted in temperate Kashmir Himalayas. We analyzed soil samples from major apple growing areas of South District Kulgam for various physio-chemical properties and available nutrient status of nitrogen, phosphorus, potassium, calcium and magnesium. The soils varied from silty clay loam to loam in texture with pH and organic carbon ranging from 4.97 to 6.24 and 1.52% to 2.78% respectively. The available N, P, K, Ca and Mg ranged from 152.32 to 428.62, 9.85 to 24.39, 206.86 to 464.92, 209.78 to 501.12, 509.43 to 621.23 Kg ha-1 respectively. Almost all samples were found to be in low to medium range in pH and electrical conductivity indicating soils are slightly alkaline and non-saline in nature.

Apple (Malus domestica Borkh.) one of the rosaceous group is native of Asia Minor to western Himalayas. High density apple orchards developed on semi dwarf rootstock like MM 106 have become common in many apple growing regions of the Kashmir especially North Kashmir. Suitability of soil as a medium of plant growth depends on both its physico-chemical properties and nutritional status. As per the results soils were slightly acidic to slightly alkaline and ranged statically from 6.55 to 7.52 in surface and 7.31 to 7.78 in sub-surface soils. The highest values of organic carbon in surface and sub-surface soils were found in orchards located in high altitude followed by mid and low altitudes orchard soils. The available nitrogen, phosphorus and potassium content varied significantly with altitude and the higher values were observed in HDP apple orchards located in high altitude. The available nitrogen and phosphorus showed a decreasing trend while as available potassium showed irregular...
A total of thirty six soil samples collected from twelve representative pear orchards were analyzed for fertility parameters using the standard procedures. Interestingly, results revealed that pH showed significant (p<0.05) but electrical conductivity recorded non-significant variation with altitude and depth. Significantly higher organic carbon content (1.16%) was recorded at high altitude and in surface soils. Significantly higher amount of calcium carbonate (p<0.05) was recorded in sub-surface horizons of mid low and high altitudes. The cation exchange capacity recorded was significantly higher in mid altitude and in sub-surface soils (p < 0.05). Available N, P and K were recorded significantly higher in pear orchards at high altitude as well as surface soils (p<0.05) whereas Ca recorded non-significant variation with altitude and depth. Significantly higher Mg (286.24 ppm) and S (11.13 ppm) amounts were observed in surface soils only. Zn and Cu showed significant decline with altitude and depth with higher amounts in surface soils of high altitude whereas Mn and Fe observed non-significant variation. However, B and Mo observed significant decline with depth (p<0.05) but non-significant variation with altitude.

The present study was carried out in Dryland Research Farm Dr Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra to characterize and classify the soils. Thirty-four surface soil samples were collected and analysed for various physical and chemical properties in the laboratory as per standard methods. The results indicated that soils under study were neutral to moderately alkaline in reaction with pH ranging from 7.5 to 8.07. The electrical conductivity (EC) data indicated that the soils are non-saline and are free from soluble salt hazard. The organic carbon content of soil was medium to high and it ranged from 0.41 to 0.93%, while the free calcium carbonate content varied from 2.8 to 6.9% indicating that these soils are moderately calcareous to calcareous in nature. The data of exchangeable cations showed that the calcium was the dominant cation followed by magnesium, potassium and sodium. The Ca/Mg ratio varied between 3.25 to 4.72. The CEC of soils varied from 52.6 to 62.9 ...

Vertical distribution of DTPA-extractable micronutrient cations (Zn, Cu, Fe and Mn) and their relationship with various soil properties were studied in sixteen profiles of orange orchard of Tamenglong district of Manipur. The DTPA-extractable Zn, Cu, Fe and Mn content were greater in the surface soils than the sub-surface horizons. In most of the profiles the value of Zn, Cu, Fe and Mn ranged from 0.20 to 1.75, trace to 0.80, 5.80 to 42.10 and 0.35 to 39.55 mg kg-1 , respectively. The content of DTPA-extractable Zn, Cu, Fe and Mn were higher surface and gradually decreased with the depth. DTPA-extractable Zn was found deficient in 73 per cent, marginal in 16 per cent and sufficient in 1.50 per cent in the soil samples while Cu, Fe and Mn were sufficient in all soils except one profile in Cu and Mn. Multiple regression coefficient analysis showed that the extractable Zn, Cu, Fe and Mn content were influenced by silt, EC, Al2O3 and Mg to the level of 0.77, 0.80, 0.73 and 0.66, respectively. However, these micronutrient cations were significantly contributed only by silt and EC.

This study was conducted to assess the fertility status of different altitude of apple orchard and their effect upon soil nutrients and to study the relationship between different altitude and their availability. Seven different orchards located in 2800, 2700 2600, 2500, 2400, 2300 and 2200 at Apple Zone, Raskot, Kalikot were selected as treatments. They were replicated three times in Randomized Complete Block Design. Composite soil samples were collected in each study site from 0-3 ft soil depth in ‘W’ pattern from each plot. Analyses of soil samples were done in regional soil testing laboratory, Surkhet for chemical properties. There was a significant effect (p<0.05) of altitude on soil macronutrients except available potassium level. Maximum amounts of soil organic matter, acidic and soil rich in nitrogen and phosphorus were found in 2800 masl whereas more basic soil , poor soil organic matter and soil poor in nitrogen and phosphorus were found in 2200 masl.

Micronutrients status and management in orchards soils: applied aspects
Average yields of our orchards (9 tones ha -1 ) are much less when compared with the world average of 25 tones ha -1 , which is mainly blamed to imbalance fertilization. Technical Services Wing of Fauji Fertilizer Company is the pioneer one in fertilizer sector, which is providing macronutrients as well as micronutrients analysis and recommendations facilities to farming community throughout the country absolutely free of cost. During a period of seven months, 329 soil samples of various depths collected throughout Pakistan from citrus, mango, guava, banana and apple orchards were analyzed for available iron, copper, manganese, born and zinc status. The results reveal a wide spread deficiency of zinc, boron, followed by iron throughout the country while the deficiencies of copper and manganese have also been observed occasionally. Due to restricted mobility of iron, zinc and boron in plant tissues and keeping in view plant physiology, the authors are of the view that as orchard crops try to accumulate maximum amounts of essential nutrients before flower formation so micronutrients foliar sprays should be made preferably after fruit harvest and before flower formation in addition to recommended deficiency doses already applied through soil. To make up the deficiencies, various management strategies and future options have been discussed in detail in this paper.

A total of forty five soil samples collected from twelve representative profiles of high density apple orchards were analyzed for fertility parameters (Zn, Cu, Mn, Fe and B) using the standard procedures. Interestingly, significant differences are found in different micro nutrients. Micronutrients shows irregular trend with altitude but almost all micronutrient were found in adequate amounts in different altitudes (High, Mid and Low). Depth also shows an irregular trend in micronutrient concentration and usually higher amount of micronutrients were found in surface soils than sub surface soils in all three altitudes, over all mean surface micro nutrients of all three altitudes were higher in surface soils (1.91, 2.32, 56.66, 59.54 and 1.35) than sub surface soils (1.35, 1.68, 49.51, 51.16 and 0.97). All micronutrient shows positive correlation between soil available micronutrients with that of leaf micronutrients both in surface and sub surface soil. Present study though first of it...

The distribution of K forms (water soluble, exchangeable, non-exchangeable, mineral and total K) in two apple (cv. Royal Delicious) orchards differing in fertilizer management practices located in the Kumaon region of Uttarakhand was investigated. The apple orchard at Mukteshwar is managed by the conventional fertilizer management practice, and the other at Dutkanedhar is managed organically. At Mukteshwar, the distribution of water soluble, exchangeable, non-exchangeable, mineral and total K was 0.23, 0.86, 5.46, 78.2, and 86.7 cmol kg-1 , respectively. Further, soil analysis revealed that both the soils contain very high levels of available K (>350 mg kg-1). Leaf K content in orchard of Dutkanedhar was deficient (0.81%) with the appearance of K deficiency symptoms as necrotic leaf edges; whereas, the same at Mukteshwar was recorded as sufficient (1.93%). The positive and significant correlations were observed between available and water soluble (r= 0.78), available and exchangeable (r= 0.45), exchangeable and non-exchangeable (r= 0.33), non-exchangeable and mineral (r= 0.77) and mineral and total K (r= 0.95) in the orchard of Mukteshwar. It was concluded that K requirement in apple could not be satisfied entirely through addition of organic manures only, and thus, K fertilization is indispensable.
