To understand why coconut palm fiber is a extra growing sensitive from an agronomic power point of aspect , it is of import to analyse the differences between a soil crop and a coir crop and compare the main factors that return tension at the ascendant spirit level .
The behavior of a plant is broadly influenced by the micro - climate in the nursery and the rhizosphere where it develops , explains Juan Manuel García , Product Manager at Projar . “ Therefore , using the highest timber coir fiber as a base will countenance the maximal vegetative and rich response of the crops . Micro - climate stipulation will always be common in any productive system , whether soil or hydroponic , therefore , we must look for differences at the ascendent level . "
Projar is one of the greatest proponents of this case of craw . Manuel shared the five types of stress that a root system can suffer :
Water stressThe assimilation of piss by the origin is affected by two force . On the one helping hand , the intercellular substance potentiality is the force with which water supply is retained by the root organisation . On the other hand , the osmotic potentiality is generated due to the ions dissolved in the medium ( salinity ) .
In a land craw , once the water rest is reached after irrigation and field mental ability , a H2O retentivity force is create eminent than that found in Cocos nucifera fiber . These values are 5 - 30 KPa for soil and 1 - 5 KPa for coconut tree fiber .
According to these time value , we can affirm that a flora grown in coir will want to make a depleted energy expenditure equate to a plant in soil to absorb the same social unit of volume .
salt stressThis eccentric of stress negatively affects water absorption . In soil , ion mobility is powerfully affected by two reason : CEC ( Cation Exchange Capacity ) and the chemic complexity of the dirt itself . In an constitutional substratum such as coconut character , the cation - type ions are more fluid , and the CEC is occupy by Calcium cations . In this case , the table salt conglomerate on the substrate can be easily washed away . Therefore , it is potential to sustain a unchanging horizontal surface of salinity , which does not go on in a soil .
Stress due to oxygen deficiencyThe root involve oxygen to respire , steep urine and nutrients , and perform other metabolic activities . The pore infinite is the balance of the full volume that a substrate has when it has been saturated with water and has drained . The porosity in coir is high and coarse enough to allow air to occupy a minimum of 30 - 35 % of the entire volume like a shot after irrigation . With this we assure the root the atomic number 8 it needs without having to endure periods of waterlogging as occur in a soil .
Temperature stressThe root is extremely pendent on temperatures both in its biological activity , ontogenesis , and ontogenesis , as well as in its functional activeness . The thermic inactiveness of coir , being of constitutive descent , is quite high and guarantees greater temperature stability in the root environment .
Stress due to pathologiesThe risk of origin diseases is enhanced in soil crop . The soil is a uninterrupted metier as there are no insulate barriers between a diseased flora and its neighbour . The cultivation in coir with isolated building block is much well arranged to void infection due to the difficulty of the cattle ranch of the disease .
Projar , with more than 35 eld of experience in the market , has created an consultative manual on the basics of raise with coir , which are the crop that are best adjust to hydroponic cultivation and the rapid return on investment in this system polish .
