Nitrogen cycle and availability
Where does nitrogen come from? Nitrogen enters the soil through organic matter such as manure and plant residues. More than 90% of the nitrogen in the soil is in these forms and becomes available only after decomposition by microorganisms. Nitrogen is also added through fertilizers, which are produced from atmospheric nitrogen (N2) that is converted into ammonia (NH3) for use in fertilizers. Nitrogen loss - what can hurt your plants? Leaching. The nitrate form of nitrogen (NO3-) is highly soluble…

Corn and soybeans: signs of potassium deficiency
Corn: In maize, the edges of the lower leaves turn brown or yellow. This is accompanied by a striped appearance of the rest of the leaf. The leaves turn a very light green color, which can be similar to symptoms of other micronutrient deficiencies (see below). Soybeans: On soybeans, the leaf margins turn light green to yellow. These symptoms first appear on the lower leaves and then spread to the top of the plant. What can potassium deficiency be confused…

How corn absorbs Nitrogen during the growing season
Stages of nitrogen absorption: Initial Phase (V1-V6): At the very beginning of the growing season, when corn is just germinating (V1 to V6), nitrogen demand is relatively low. At this time, the plant is concentrating on forming its root system and first leaves. Although nitrogen is important for this process, its uptake at this stage is minimal. Active Growth Phase (V6-VT): From V6 (the sixth leaf stage) to VT (the tassel stage), the need for nitrogen increases significantly. At this…

WHAT ADDITIONAL INFORMATION IS REQUIRED TO RECEIVE RECOMMENDATIONS?
For a standard laboratory analysis, you need to know the planned yield of three different crops (if you do not clearly understand the crop to be grown next season) or one crop with three different yield options (if the crop is clear but the grower wants to compare costs for each planned yield). Any additional information will also be useful, such as information on the presence or absence of irrigation, rainfall in the region where the fields are located, last year's predecessor crops and their yields, and more.

WHAT SHOULD I DO IF THE PLANTS IN ONE AREA OF MY FIELD LOOK GREEN AND HEALTHY, BUT IN ANOTHER?
For comparative analysis, we recommend that plant samples be taken from each of these sites. It is also useful to include in the comments all information about management practices in these areas (if there were any differences). After harvesting, soil samples are also recommended to be taken separately from each plot.

DO I HAVE TO PAY SEPARATELY FOR RECOMMENDATIONS?
No, because the fee for recommendations is included in the total cost of conducting a full comprehensive agrochemical analysis.
