N-tester GreenSeeker

Portable handheld sensor GreenSeeker ® – is a simple and affordable assistant agronomist which is designed to measure and assess the state of the plant, the calculation of fertilizer and crop forecasting. The unit is on-line directly in the field by providing recommendations for nitrogen fertilization to date in real time on a certain grade. Using the method of calculating NDVI instrument will respond to the need for nitrogen plants, the general health of culture on the basis of which the farmer or agronomist can do predetermine steps that will prevent the introduction of excess fertilizers that could be detrimental to the crop.

 How it works?

 When you click on the sensor device emits short light rays in the red and infrared light reflected from the surface of the plant leaf partially dissipated, and the remnants of fighting back in the trap detector is a device that analyzes the data and displays it on the screen. These data are the NDVI index for the plant which ranges from 0.00 to 0.99 and the higher the figure the better health and less need for nitrogen feeding (depending on the variety, culture, etc.).

To obtain relevant results for a particular field, you must take measurements of biomass in different parts of the field and averaging the data. To provide accurate information on the measurement device is held at a distance of 60-120 cm from the plant. Field sensor measurement oval and increases depending on the altitude, so we recommend performing the measurements at a constant height of about 1 m.

The kit includes:

– Manual sensor GreenSeeker ®

– Charger

– Enhanced battery (provides 5 hours of work)

– Cover

– Strap

– Instructions

– Recommendations developed by GMBH “Agri Land”

Now portable GreenSeeker handheld can be used to calculate the rates of fertilizer for the followingagriculture crops:

 Spring wheat

 Winter wheat

Soil Compaction Meter Wile Soil

What is the density meter of soil?

   Density of soil or penetrometer – a device that measures the density /resistivity of the soil when it is introduced into the soil (standard ASAE S313.3)
   Through the use of soil Wile Soil densitometer, you can:

  • Promote the development of the root system of plants
  • Improve the effectiveness of fertilizers
  • Ensure the penetration of moisture into the deeper layers of the soil and prevent water stagnation in the surface layers
  • Reduce the cost of tillage
  • To save you time and money


How to solve the problem of soil compaction

   Once you’ve figured out at what depth to be plow sole, you can:

  • Restrict the movement of agricultural equipment in the areas of seals
  • Start planting cover crops to improve soil water regime
  • Plowing their fields with the help of equipment that can penetrate into the deeper layers of soil


The optimal time to measure the density of the soil

   The optimal time to determine the density of the soil is considered to be an early spring – the period before plowing. The soil should be moist enough, as the moisture content in soil and its structure will affect the densitometer readings.
   It is recommended to compare the readings of the same soil type with the same moisture content. To understand the differences, carry out the measurement of the density near the fence, and then in the field – the results are quite different. To obtain a reliable measurement result, it is necessary to carry out several measurements in different places of the field and calculate their average.


To obtain reliable results, spend a few measurements in the same area of the field. Just check out a fewareas.

The density
  • Green segment (0-14 kg/cm2). Favorable growing conditions.
  • Yellow segment (14-21 kg/cm2). Suitable growth conditions.
  • Red segment (21 kg/cm2 or more. Unfavorable conditions for growth.

    Density is supplied with two tipsa diameter of 1.27 cm for measuring the density of the solidsubstrate and a diameter of 1.91 cm for measurements in the soft groundOn the face of the densitometer for each tip has its own scale. It is based on a unit of measurement Psi – pounds persquare inch.

N-tester SPAD

Nitrogen tester SPAD


Chlorophyll is the green pigment found in all green plants and is essential for photosynthesis.

Efficient use of nitrogen (N) fertilizer is important to economical agriculture production and to

the quality of ground and surface waters. The chlorophyll meter is a good way to testing for N.


-Precision:  ± 1.0 SPAD

-Repeat: ± 5.0 SPAD

-Temperature of testing: 0°С  to 50°С

-Storage range: -22 to 50°С

-time for testing:  2s

-testing area Diameter:  3mm

-Stored datum: 30 Groups -50°С

The optimal number of N-fertilizer remains unknown up to the start of the growing season.

  • Dividing of N-fertilizer at 3-4 doses allows make flexible solutions, depending on the growth and weather conditions.
  • Optimal plants nutrition requires the active management of crop condition with the help of agronomists.

  • Using the SPAD N-Tester, you can simply, accurately and quickly determine the need for nitrogen your plants directly into the field.


Please, when setting up the SPAD N-Tester, pay attention to:

  • Growth stage: recommendations for N-fertilizer relate only to the growth stages VVSN 30-32 (growing) and VVSN 37-51 (first appearance of thin leaves before the start the ears).


  • Measuring point: measurement should be taken right in the middle of the plate the youngest fully developed leaves (see figure below.). The measurement of not fully developed leaves could lead to overrated recommendations.


  • Sorts: The difference between sorts is leveled through annual updates adjustment coefficients, which are given with the application map, as well as application chart, can be drawn by agronomist.
  • The sulfur deficit: S-deficiency leads similarly to the lighting leaves. When setting up the SPAD N-Tester, you need to install S-sufficient rate. We recommend that the S-deficit be covered at a very first dose, so that the application of the SPAD N-Tester prior to the second and third doses did not raise any S-deficiency. Other nutrients have no significant impact.


  • There is no impact on the measurement of N-Tester by the time of the day, pesticides or moisture on the leaves, strobile and the yield level.


  • High-quality wheat: There is no additive for the growing of high quality wheat in recommendation of N-Tester. Please consider the relevant recommendations crop sector.


  • Your experience: The SPAD N-Tester can not show the N-earth stocks that plants still can not take because of the prolonged drought. Then rely on your experience in the interpretation of the N-Tester measured value.


SPAD N-Tester can help you optimize the N-fertilizer in the economic and environmental terms.


Numerous own and independent field research, as well as of many years tests cover the accuracy of the N-fertilizer recommendations using the SPAD N-Tester. The N-fertilizer using the N-Tester provides you with agronomic success.
