|
For taking soil sample, probe, drill or shovel shown in figure are used. |
|
|
|

|
|
|
|
Soil samples are not taken over a flat line extending from one end to another end of field, orchard or greenhouse but are taken in 15-20 steps over zig-zag line as shown in the figure. |

|
Hole with 30 cm depth in V letter shape is opened from each point in zig-zag line corner while taking soil samples from the areas where one year plants or vegetable are grown. Then, one surface of this hole will be levelled and a slice of soil will be taken in 3-4 cm thickness from this surface. Taken soils are accumulated in a plastic bucket. |

Soil sample is taken, as described in the figure, from orchards and vineyards from two different depths as 0-30 and 30-60 cm. These taken soils are accumulated in different plastic bucket. |

Soil samples taken in the same way from each point are mixed well. Maximum 1 kg soil sample out of these mixtures are sorted out by cleaning it from cobbles, litter and other foreign substances and put into plastic bag by tagging and delivered to laboratory without wasting time. |

Methods used in soil analyses conducted in Soil Analysis Laboratory established and operated within the body of our institution are internationally accepted methods and specifically compatibility of soil analysis methods with the soils of our country has been proven by various universities and research institutions. Soil analyses are conducted for the purpose of putting forth efficiency potential of agricultural soils and to determine the levels of plant nutrition substances provided for plants to be grown thereon.
To this end, analyses of pH, carbonates, active lime, soluble total salt, saturation, body, organic substance, total N (Nitrogen), P (Phosphorus), K (Potassium), Ca (Calcium), Mg (Magnesium), Fe (Iron), Mn (Manganese), Zn (Zinc), Cu (Copper), B (Boron) and S (Sulphur) are conducted in soil samples and their results are interpreted and fertilization programs are prepared by considering nutrient requirements of plants to be grown. In this way, fertilizer provision is enabled as required, efficiency balances of our extremely valuable agricultural lands are protected and more healthy agricultural products are obtained. When aforementioned matters are taken into consideration, it has been concluded that establishment of agricultural purpose laboratory (soil, leaf, water, fertilizer and similar chemical analyses etc.) would be beneficial and establishment of laboratory has been carried out by finalizing the studies started in respect with establishment of laboratory in a comprehensive and rapid way. 3 personnel as Agricultural Engineer, Chemist and Laboratory Assistant serve in our laboratory.
HOW SHOULD LEAF SAMPLE BE TAKEN?
1- If type, variety and development of leaf samples are different, separate samples should be taken.
2- Leaf sample should be taken sufficiently as to land size and plant variety by walking along diagonals or zig-zag shapes in field, garden or greenhouse.
3-TSample is taken out of one year plants from the youngest leaves that have completed its general development (sun flower, wheat, maize, sugar beet).
4- - Sample to be taken out of multiyear plants (fruit tree) should not be larger than 20 decares. Leaf sample should be taken from 20 % of the number of existing tree. Leaves should be taken over suckers with one year and from each side of tree.
5- Plant samples should be tagged inside cloth bags and should be delivered to laboratory within the same day. If delivery to laboratory is not possible, it should be stored in refrigerator.
6- Name surname, province-district-village, location, telephone, area, plant name, type and age (if it is a plant) should be indicated on tags.
FROM WHERE LEAF SAMPLE SHOULD NOT BE TAKEN?
1-Dead or ailing plants,
2-Plants with insect or damaged plants,
3- Plants that have been affected temperature or moisture and plants covered with soils,
4- Following disinfection and fertilization,
5- Plant sample is not taken in rainy days. It should be noted that plant is not wet.
