EARTHBIOTICS effect in foliar dressing.

Foliar  dressing  is  a  unique  opportunity  to  influence  growth  and  development of plants during the whole vegetation period, it creates favorable conditions for formation of every yield structure element. Main reasons for foliar dressings use are:

Agility

The    substances    after    being    absorbed    via    leaves    follow    the    same    path    of metamorphoses as if they were absorbed via roots, but 8-10 time faster.

Increased coefficient of basic fertilizers application.

When nutrients get to intercellular space of leaves, it creates a misbalance of elements concentrations.  With  foliar  dressings,  a  plant  compensates  the  problem  occurred by activating absorption of nutrients from soil, what makes the application of the latter by 30% more effective.

Fertilizer elements delivery with a weakened root system.

When a root system is poorly developed, sick or root fibrillas are dying due to drought, leaf-feeding is the only way to provide plants with nutrients.

Decrease in pesticide-caused stress.

While  planning  chemical  treatments  for  weeds  eliminationthe  highest  results  are reached by combining application of herbicides and growth stimulators.

Application of EARTHBIOTICS allows restoring a normal physiological state of crops and to eliminate consequences of stress caused by herbicides with minimal loss. Pesticides are toxic substances, so they harm not only pests but also the cultivated crop itself, which causes slowing down of all physiological and biochemical processes inside the plant and accumulation of decay products.

Boosting plant immunity to diseases.

Macro-  and  microelements  participate  in  synthesis  of  cells  wall  building  materials (cellulose, lignin, pectin) and boost water-retention ability of tissues. Robust cells wall and high turgor  are a  barrier on  the  way  of fungous and bacterial  microflora.  With a timely   provision   of   the   whole   complex   of   macro–   and   microelements,   plants launch active and passive forms of immunity faster.

Increase in drought and frost resistance, resistance to salinization.

Reproductive development optimization.

The  major  role  in  this  process  belongs  to  B  and  Zn,  macro-  and  microelements accelerate     pollen     germination,     boost     its     vital     activities,     influence     buds development

and seeds ripening processes.

Control of sugars translocation from leaves to storage organs.

Decrease in loss during transportation and storage.

Recommended scheme of leaf-treatment (grain crops, for instance):

1sttreatment (phase of tillering – beginning of stem elongation):

EARTHBIOTICS  0.4-0.5  l  +  herbicide  +  water-soluble  mineral  fertilizers  (UAN, liquid complex fertilizer, etc.) (or without them) shall be dissolved in 150-200l of water per

1 ha.

In Russia, the following scheme of grain crops treatment is gaining popularity:

1st leaves treatment (phase of tillering – beginning of stem elongation):

Herbicide + 0.4-0.5l/ha of EARTHBIOTICS + 5-7 kg of carbamide shall be dissolved in

150-200 l of water per 1 ha.

 

Why was carbamide chosen as a nitrogen additive?

It is well known that nitrogen can be in 3 forms:  amidic (carbamide), ammoniac and nitrate. The most mobile and available for root systems is nitrate form. Nitrates can be     available     to     plants     for     a     very     short     period     of     time,      usually     such period  lastsapproximately   10-15   days,   after   that   they   get   washed   down   to   the lowest  soil horizons.

Ammoniac  form  also  accesses  plants  through  their  rootsbut  only  after  being decomposed  by  microorganisms  to  nitrate  formAmidic  solution  (carbamide)  is  well digestible through a leaf apparatus. In order to get absorbed by roots, it has to go through a long chain of subsequent transformations that take time and require certain conditions.

2ndtreatment  upon  vegetation,  for  instancefor  grain  crops  (stem  elongation phase   –   milky-wax   ripeness).0.40.5   l/ha   EARTHBIOTICS   +   fungicide   +   insecticide (if necessary)   +   5-7   kg   of   carbamide   per   1   ha   (necessary   amount   of   carbamide shall   be  dumped  on  sprinkler  tank  net  and  then  water  shall  be  poured  through  itthen water shall be  added  to  the  solution  giving  a  total  volume  of  150-200  l  per  1ha. Nevertheless, while   preparing the   solution,   first,   water shall be   added in   the   sprinkler tank   (1/3   of   the   volume),   then   the   nece1s2sary   amount   of   carbamide,   then   herbicide,

fungicide  or  insecticide,  depending  on  the  purpose  of  the  treatment,  after  that,  a  missing quantity                                 of                                 water                                 shall                                 be added, and the solution shall be thoroughly mixed with a stirrer of the sprinkler. Why is it important  to  follow  this  procedure  precisely?  –  The  thing  is  that  carbemide  (nitrogen) is heavier than water, and if we put the fertilizer in the sprinkler tank first, it will end up on the bottom of the tank and in pipes, which will result in that at the first 500 m of work in the field the whole carbamide dose will be out.

It   is   known   that   foliar   dressing   with    mineral   fertilizers   is   the   most efficient agricultural practice used for increase in grains quality.

3d  late foliage application  promotes  improved  quality  of  grainsand  in  this case

nitrogen plays a key part.

However,  its  deposits  in  the  soil  run  very  low  by  the  time  of  grain  formation of autumn-sown  wheatNitrogenous  nutrition  of  plants  can  be  significantly  improved only with the help of late nitrogen dressing of autumn-sown wheat crops during the period of dough stage and “lemon leaf” stage.

Agrochemistry theoretically justified and  developed  a  special  practice  for  grain quality   improvement   –   foliage   dressing,   the   efficacy   of   which   depends   on   many factors:    plant    development    phase,    forms    and    dosage    of    nitrogenous    fertilizers, concentration of the solution, weather conditions, biological peculiarities of species, etc.

following scheme: 0.5l/ha  of Earthbiotics+ 5-7 kg of carbamide + 150-200 l of water per 1 ha. The treatment shall be carried out in the morning (when there is no dew) or in the evening, during cloudy weather or night.

If   the   dressing   with   carbamide   solution   and   EARTHBIOTICS   was   carried   out properly, the contents of protein in grain increased by 1/2-4.2, and of raw fibrin – by 3-7%. It allows selling the grain for a higher price, which not only pays for all additional expenses, but also provides farms with significant profit.
