This billet will discuss the soil and ground requisite for lily cultivation .
Soil : The soil is the top layer of the terra firma ’s Earth’s crust , but the definition in soil science is more specific , namely that layer of the earth ’s crust that is root by plants ( the rhizosphere ) , or in which soil - forming processes take place . allot to this definition , solid rock and the wet , unripe ( ' in which no dirt has formed ' ) undersoil of wanton sediments are not part of the soil . The soil - forming processes leave to changes in the composition of the soil , which become visible , among other thing , in the formation of soil skyline . The term soil and reason are often used interchangeably , but the latter has a broader substance . grunge science is essential for understanding natural processes and the performance of ecosystems . homo make use of soil subprogram in many different path .
Ground : Ground is a mixture of weathered upstanding textile ( deposit ) , water , and air that happen on the worldly concern ’s surface or ( flat ) below . The non - weathered solid stuff is call off rock . The weather process is a resultant role of the action of frost and thawing ( alternately freezing and thawing piddle in rock crevices ) , and of Sunday , rain , and steer on rock , which eventually take to fractures in the rock . Pieces of rock come loose as a answer , roll down , after which the smaller portion are carry by rivers towards the river delta . Due to further outwear , smaller and smaller parts are formed , successively gravel , sand , and ultimately silt : the mineral element of the ground . Peat is created by the death and rotting of plant underwater in low - atomic number 8 conditions . Humus is created by biodegradation of dead plants in oxygen - rich ' tellurian ' conditions ( on land ) . Peat and humus are the constitutive constituent of the primer coat .
decision : The above definitions of soil and soil show that earth is the physical part and soil is the living part . The search for suitable plots for the cultivation of lilies continue through the undermentioned steps : First of all , it must be determined whether there have been lily on the plot before and if so , how many years ago . To ascertain this , you could employ a instrument such as boerenbunder.nl * . Naturally , preference is always move over to fresh arable land without nematodes . If this is not sufficiently useable , you’re able to opt a plot of land where there have been no lilies in the last 6 years . This period of time is necessary to decimate the soil and riffle nematode population leave behind after the premature cultivation of lily . To go after away the last nematodes , another harvest of Marigolds ( Tagetes ) is sow as a preliminary fruit for the lilies . Nematodes hate this industrial plant . Tagetes is also an important nutrient for the soil , just like brute manure and compost . It increases the organic matter message of the territory .
- boerenbunder.nlWith a subscription to boerbunder.nl you could see for every plot of ground in the Netherlands what has been grown on it in the last 10 year . At boerenbunder.nl you’re able to also see how many percent of ponderous stiff , light clay , with child remains , light clay , Baroness Dudevant , and loam the soil visibility is built up and the groundwater level of the plot is expose . Boerenbunder.nl also offers an up - to - escort flora single-valued function obtained from satellite images on which you may see per patch when , for deterrent example , it was sown and harvested , the superlative difference of opinion of the patch and whether there are ditches and how long they are , and what type of ditch they are . Finally , it is indicated whether the plot falls within a Natura 2000 surface area .
Then one looks at the forcible condition of a plot and thus the strong-arm properties of the priming coat .
Ground requirements for lily cultivation : For lily bulb cultivation , the forcible condition of the flat coat is of decisive importance for obtaining a good intersection that can be planted and harvest automatically . The ground must therefore meet the follow requirements .
1 . sound moisture and air permeabilityInformation from the landlord of the patch plays a major role in determining moisture and air permeability . He know well than anyone where the speculative spots are . In guild to get an even better film of the moisture and air travel permeability of the plot , a laggard can be used during the preliminary cultivation for the lilies , with which one can observe from above at which place the crop express ruffle in growth . In almost all cases , this is a good indicator of the moisture and strain permeability on site . If this is only a small patch , this need not be a cause not to hire the plot of ground , because it can be decided to skip this small spot during planting . However , if it concerns larger areas , it must be find out what causes the disturbed growth of the pre - crop . If it appear that the overall drain of the plot is not good , it can be decide to run out before the commencement of lily culture . If the hapless wet and air permeability of the game is triggered by superficial compaction triggered by heavy machinery , thoroughgoing mechanical earth preparedness will suffice . If the short moisture and air permeability of the plot is cause by compaction of the ground because of a too eminent content of o.k. clay fraction or too blue a content of organic matter , it is advisable not to practice this plot of land for the finish of lily .
2 . Good machinability : A plot where lilies are grown must be suited for crop with heavy machinery . To learn whether this is the case , it is sufficient to correspond this with the landlord and growers , and contractors in the immediate vicinity of the secret plan .
Soil requisite for lily cultivation : For lily bulb refinement , in addition to the physical condition of the soil , the condition of the soil life present is of decisive importance for obtaining a good product . The land must therefore meet the come requirements .
1.PathogenenThe main pathogens ( pathogen ) of the Lily occurring in the soil are Fusarium , Rhizoctonia , Phytophtora ( Wet infantry rot ) , Pythium ( Root decomposition ) , Botrytis ( Fire ) . A field pathogenicity test is used to determine the disease pressure of the ground of a plot of ground to be rent . The value of Rhizoctonia , Phytophtora , Pythium , and Botrytis are the least of import here because an infestation by these pathogen can be sufficiently prevented by mean value of the correct cultivation measures . However , if the field pathogenicity test in the soil establishes a too high percentage of Fusarium , the plot of ground is not desirable for lily cultivation because experience shows that Fusarium plague can not be prevent by means of the right cultivation metre .
2.Acidity ( PH)For which group of lily the patch is desirable depends on the sourness of the grime . Asiatic and Longiflorum hybrids prefer a pH of 6 to 7 for optimum growth and Oriental hybrids favor a pH of 5.5 to 6.5 . If a plot conform to both the soil and soil requirement for lily refinement , the plot is suitable for educate lilies .
