Dr.Crop Organic

Humic acid is naturally occurring, organic substance found more in forest soil and
rich in oxidized low rank coal, lignite, peat, etc. It is not a chemical fertilizer but a organic
bioproduct. It increases water retention, retains nutrients and enhances microbiological
activity, enzymes in soil, etc. The organic matter on biodegradation is converted in to
humus, which contains humic and fulvic substances. The humic substance contains
various functional groups of carboxylic, carbonyl, phenolic, alcoholic with higher
molecular weight of 40,000 to 70,000 and higher cation exchange capacity (100-130
meq/100 gm). Lignite contains more of humic acid. Whereas some of the oxidized coals
contain higher content of fulvic acid; both of them are plant growth stimulant and
beneficial to crops.
General Properties and Constituents:
pH : 8.0-9.5
CEC : 100-130 meq/100 g
Carbon & Oxygen: 90-95 %
Nitrogen & Hydrogen : 3-5%
Organic Carbon : 18.0-22.0%
sulphur, manganese, iron, molybdenum (0.10-6.0%), copper, zinc, magnesium,
boron (20-200 ppm), etc. It is soluble in water and has high biological activity in soil
Uses: To all commercial crops, cereals, pulses, oilseeds, vegetables, trees, orchards,
green house crops, ornamental plants, grass lawns, nurseries it can be sprayed in soil
before planting and foliar spray in two or three stages on plants before flowering for best
Soil application: Liquid potassium humate may be applied 35 ml/m area before planting
/ sowing / during irrigation. For aged or grown up trees, the dosage can be increased to
about @ 200 ml per tree. Solid potassium humate may be applied @ 10 kg/hectare for
all crops.
Foliar spray: Dilute 1 liter of liquid in 30 liters of water, then spray to all crops before
flowering, ornamental plants and grass lawn; once in 30 days in morning or evening for
better results and may be combined with fertilizer spray also.
Functions of Dr.Crop :
1) Promoting the formation of good soil structure, increasing the cation exchange
capacity (CEC), water-holding capacity, and the capacity of fertilizer retention.

2) Promoting nutrient uptake by plants and enhances the soil's ability to chelate nutrients
and to promote exchange of nutrients between plants and the fertilizers being applied.
Thereby reducing the loss of applied fertilizers from leaching and run off. Because they
are already a part of a certain organic structure, the Dr.Crop chelate complexes with
microelements can penetrate into the cell more easily than ordinary ions.
3) Stimulating beneficial microbial activity and root growth. Long-term research showed
that humic substances bond many organic and nonorganic substances into poorly
soluble or insoluble compounds, so it reduces the toxic effect of residual amounts of
herbicides, soil polluting radio nuclides, heavy metals, and other harmful substances, as
well as radiation and chemical contamination.
4) Improve crop stress-resistance ability, it has been proved that the Dr.Crop help to fight
the effect of droughts and ensures their drought resistance. Long-term experience in the
use of Dr.Crop has shown that their presence is important during all stages of plants’
development but particularly vital in the early stages. The pre-planting treatment of
seeds is very important. Even before germination begins, vital forces are awakened, and
the immune system is stimulated.
5) Increase the yield and quality of various crops. Dr.Crop contain more biologically
active components, and it directly affects their use.
Dr.Crop Benefits
Physical Benefits:
Dr.Crop is physically modify the structure of the soil.
Improve the structure of soil: Prevent high water and nutrient losses in light, sandy
soils. Simultaneously convert them into fruitful soils by way of decomposition. In
heavy and compact soils, aeration of soil and water retention is improved;
cultivation measures are facilitated.
Prevent soil cracking, surface water runoff and soil erosion by increasing the
ability of colloids to combine.
Help the soil to loosen and crumble and thus increase aeration of soil as well as
soil workability.
Increase water holding capacity of soil and thus help resist drought.
Darken the color of the soil and thus help absorption of the
sun energy.

Dr.Crop chelate nutrient compounds, especially iron, in the soil to a form suitable for

plant utilization. Thus, the nutrient supply of plants is optimized. High increases up to
70% in yield, accompanied by a reduction up to 30% in the use of fertilizers and
pesticides, as well as better and healthier growth of green grass, ornamentals,
agricultural crops and woods can be attained with the regular application of first-quality
humic acids. Furthermore, water holding capacity of soils is increased considerably,
which means that the use of water can be reduced substantially. Best economic results
can be obtained in light and sandy soils poor in humus as well as on re-cultivation fields.
The diverse positive impacts of humic acids are to be observed particularly in such soils.
This is true for almost all soils in dry and warm regions. As a result of the high
mineralization rate of organic substances, providing these soils with stable humic acids
is indispensable for the maintenance and improvement of soil fertility. Trials conducted
by Tamil Nadu Agricultural University, Coimbatore for four years in various agro-climatic
conditions in their experimental stations as well as in farmers’ fields on various crops
using the Dr.Crop produced by Neyveli Lignite Corporation (NLC), Neyveli have revealed
increase in yield of crops over control. Some of the research findings are given below:

Sl.No Crop Improvement in Yield
1 Rice 2.5 % to 22.5 %
2 sugarcane 5.1% to 24.1%
3 Groundnut 14% to 27.2%
4 Pulses 14.3 % to 27.7%
5 Cotton 15.4% to 24.4%
6 Tomato Maximum 16%
7 Onion (dried) Upto 47.83 %
8 Tea Upto 30 %

It has been proved that the crop yields have increased from 10 to 30 per cent apart from
reduction of chemical fertilizers, which adversely affects environment. At present there is
no source in India that manufacturers an equivalent product at such an economical rate.
At present the relative products are imported mainly from USA, China draining huge
Forex. The product has large potential for use in agriculture especially for food crops,
commercial crops like spices, pulses, grapes, coffee, tea, cashew, cotton, fruit-bearing
trees and apart from vegetables. As per an empirical study carried out by the NLC team,
with the cropping pattern in India with the cultivable land of 140 million Hectares, the
Dr.Crop requirement will be about 6.2 billion liters and with a market penetration of just
10%, the demand will be 620 million litres. NLC has proven technology for the
manufacture of Dr.Crop from lignite on a pilot plant scale with a minimum capacity of
3,60,000 liters per annum. NLC had been marketing the product to the farmers even
from the farthest places like Nasik (Maharashtra), Mangalore (Karnataka), etc. who had
gathered information about the utility of the product through Agricultural Scientists in the
Region and collected the product from Neyveli on the road. Hence, it is felt that there is a
huge market potential for the application of the product in the Indian agriculture with
appropriate marketing and promotional activities.
