SOIL TESTING

SOIL TESTING - In agriculture, a soil test commonly refers to the analysis of a soil sample to determine nutrient content, composition, and other characteristics such as the acidity or pH level.
AIM- To test soil by different methods
TOOLS - Soil testing kit , ghamela , favda , khora , etc
PROCEDURE –
1)First take 1 gram of thin solid and add in the testing bottle
2) Then add liquid nitrogen  up to 6 ml and shake it until a minute
 3)Then keep the bottle for 5-6 minutes stable then add four drops of anti 2 and anti  3 in testing bottle ,then compare the color with PH reading
 4) Now add phosphorus and do the same process Soil testing is often performed by commercial labs that offer a variety of tests, targeting groups of compounds and minerals. The advantages associated with local lab is that they are familiar with the chemistry of the soil in the area where the sample was taken. This enables technicians to recommend the tests that are most likely to reveal useful information.


Soil testing in progress
Laboratory tests often check for plant nutrients in three categories:

Major nutrients: nitrogen (N), phosphorus (P), and potassium (K)
Secondary nutrients: sulfur, calcium, magnesium
Minor nutrients: iron, manganese, copper, zinc, boron, molybdenum, chlorine

Lactometer

What is Lactometer ? Lactometer, a cylindrical vessel made by blowing a glass tube. One side of glass tube looks like a bulb with filled by mercury and another site is thin tube with scaled. For milk testing lactometer dipped in milk which we are testing. In lactometer the point up to which it sinks in the pure milk is marked after that put in water and marked at the point up to which it sinks in water. It sinks less in milk then water because as we know milk is denser then water. At lactometer there are to portions i.e. ‘M ‘and ‘W’ which is divided in three parts and marked as 3, 2 and 1. That indicates the level of the purity in Milk. Here below some steps mentioned for milk testing – Step 1 - Whenever you want to test the milk purity Find Article, you just put the instrument or lactometer in milk. Step 2 - If it sinks up to the mark ‘M’ which mentioned at lactometer that means milk is pure or if not that means milk is impure. Step 3 - If the milk is mixed in water then i...

GRAFTING

Image
GRAFTING - Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the root stock. The success of this joining requires that the vascular tissue grow together and such joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades . TYPES OF  GRAFTING - 1) Saddle graft                                               2) Bridge graft                                               3) Inarch graft                          ...
