Chloride injury can be avoided by using chloride excluding rootstock as in grape and mango.
Boron should not be more than 1 ppm and sodium should be less than 8% of sodium compared to calcium and magnesium.
For sodic soil crops like Guava/Amla and Sapota can be recommended.
Yes – By conjuncture use of water and by frequent slight irrigations will prevent salt build up.
Saline soil needs more drainage and leaching of salts. Acid soil needs liming. Alkali (sodic) soil needs gypsum application.
Water should have EC less than 1.5 dSm-1 and chloride less than 3 m.eq/l (100 ppm).
Horticultural crops suited for saline/acid/alkali soil.
Saline Soil Tomato - Banana
Onion - Mango
Brinjal - Papaya
Acid Soil Cabbage - Pineapple
Cauliflower - Papaya
Cole Crops - Citrus
Alkali (Sodic) Sapota - Chilli
Pomegranate - Marigold
Guava - Beet root.

If fertilizers are incorporated into the soil, losses can be prevented and availability of nutrients can be increased.
Broadcasting is the general method of application of fertilizers. Band application also can be followed especially for the fertilizers like phosphorous.
The fertilizers are generally applied when sufficient moisture is present in the soil. Pre-monsoon and post-monsoon period is the best (May-June and September-October).
Run the bore-well for 10 to 15 minutes and collect the water into a well cleaned bottle and bring to the laboratory.
The samples should be kept in a ice box and to be brought to the laboratory.
The samples are dried at 75oC in an Oven in the laboratory.
Recently matured leaves from all directions of the tree (N, S, E, W) should be collected.
Yes – It is better to get analyzed both soil and leaf samples for nutrients for better interpretation and to provide recommendations.
