Why is it important to conduct soil test ?
Soil test is a valuable tool for your farm as it determines the inputs required for efficient and economic production of fruits and vegetables. A proper soil test will help ensure the application of enough fertilizer to meet the requirements of the crop while taking advantage of the nutrients already present in the soil. It will also allow you to determine lime requirements and can be used to diagnose problem areas. It is very important that your sampling technique is correct as the results are only as good as the sample you take. Soil testing is also a requirement for farms that must complete a nutrient management plan.
Getting a soil test is a great way to measure its health and fertility. These tests are generally inexpensive, though well worth any cost when it comes to growing and maintaining healthy plants in the garden. So how often should you do a soil test and what does a soil test show? To answer these questions, it may help to learn more about the soil testing process in general.
Why Test Soil in the Garden?
Most soil nutrients are readily found in the soil provided that its pH level is within the 6 to 6.5 range. However, when the pH level rises, many nutrients (like phosphorus, iron, etc.) may become less available. When it drops, they may even reach toxic levels, which can adversely affect the plants. Getting a soil test can help take the guesswork out of fixing any of these nutrient issues. There’s no need to spend money on fertilizers that aren’t necessary. There’s no worry of over fertilizing plants either. With a soil test, you’ll have the means for creating a healthy soil environment that will lead to maximum plant growth.
What Does a Soil Test Show?
A soil test can determine the current fertility and health of your soil. By measuring both the pH level and pinpointing nutrient deficiencies, a soil test can provide the information necessary for maintaining the most optimal fertility each year. Most plants, including grasses, flowers, and vegetables, perform best in slightly acidic soil (6.0 to 6.5). Others, like azaleas, gardenias and blueberries, require a somewhat higher acidity in order to thrive. Therefore, having a soil test can make it easier to determine the current acidity so you can make the appropriate adjustments. It will also allow you to fix any deficiencies that may be present.
How Often Do You Do a Soil Test?
Soil samples can be taken at any time of the year, with fall being preferable. They are normally taken annually or simply as needed. While many companies or gardening centers offer soil testing kits, you can usually obtain a soil test at low cost through Oxfarm Organic Ltd. Avoid having the soil tested whenever the soil is wet or when it’s been recently fertilized. To take a sample for testing garden soil, use a small trowel to take thin slices of soil from various areas of the garden (about a cup’s worth each). Allow it to air dry at room temperature and then place it into a clean plastic container. Label the soil area and date for testing. Now that you know the importance of getting a soil test, you can better manage your garden plants by making the appropriate adjustments from your soil test results.

Grape vines not only produce sweet and versatile fruits, they add an element of drama to a garden or landscape. They are vigorous growers, and with the proper pruning, they will produce fruit with ease and can last longer than 30 years.
The crop prefers warm to hot temperatures; during fruiting, the weather must be sunny and dry. Warm environmental temperatures during fruit ripening, is important in increasing the sugar content of berries while reducing their acidity. This explains why grapes grown under irrigation in hot deserts or semi deserts are sweeter than those from cold humid areas.
The crop can grow in any soil, from sandy to heavy clays but the soil should be deep and well drained. Where the rainfall is scant, supplement it with an irrigation of 500 mm of water during the cropping season. In Kenya, the cropping season is September to March.
Irrigation should be withheld after the long rains so as to force the crop to go dormant.
In August to September, fruit buds form thus it is important to keep the plant healthy and well manured.
There are plenty of health benefits in consuming grapes for they are a rich source of Vitamins- A, C, K and minerals such as iron, copper, manganese.
Soils should be well drained. Wet soils lead to poor aeration and increased incidence of crown rot in apples (Phytophthora cactorum). Generally, rooting tends to be shallow, and wet soils will restrict development, resulting in poor anchorage of the tree and a reduced area of soil from which nutrients can be extracted. Soils with high organic matter contents are normally better structured and allow good rooting.
Irrigation is necessary on dry soils, particularly when establishing and growing young orchards. Trickle irrigation and fertigation are increasingly used. In young orchards fertigation helps increase early tree growth and brings trees into bearing earlier. Sprinkler irrigation can be used to protect the tree buds and fruitlets against frost damage.
Sowing of a grass mulch between the tree rows is common practice, which together with any clippings, helps to increase water holding capacity, infiltration rate, soil aggregation and recycling of nutrients.
Apples prefer a slightly acidic to neutral soil (pH between 5.8 and 7.0). Extreme soil pH values result in nutrient tie-up or toxicity and poor tree and fruit development. It is important to amend the pH in acidic soils by incorporating lime before planting
Tangerines are relatively cold-tolerant, making them easier to grow than oranges, grapefruits and other types of citrus. Some varieties, such as the Citrus reticulata "Dancy," are heat-tolerant and do best when summers are hot, but other types, including the Citrus reticulata "Sunburst," do best when summers are on the cool side.
Citrus species can thrive in a wide range of soil and climatic conditions. Citrus is grown from sea level up to an altitude of 2100 m but for optimal growth a temperature range from 2° to 30° C is ideal. Long periods below 0°C are injurious to the trees and at -13° C growth diminishes. However, individual species and varieties decrease in susceptibility to low temperatures in the following sequence: grapefruit, sweet orange, mandarin, lemon/lime and trifoliate orange as most hardy.
Temperature plays an important role in the production of high quality fruit. Typical coloring of fruit takes place if night temperatures are about 14° C coupled with low humidity during ripening time. Exposure to strong winds and temperatures above 38° C may cause fruit drop, scarring and scorching of fruits. In the tropics, the high lands provide the best night weather for orange color and flavor.
