can any one give me an idea about using AMF and plant residue to alleviate continuous cropping obstacles..
For your continuous vegetable cropping system you can use AMF colonized transplants and also use plant residues for mulching. For success rotational schemes are needed. I would also suggest you develop an effective irrigation system and ability to optimize compost utilization. You will can analyze the soil conditions and develop goals for soil improvement needed to support a continuous system.
to increase AMF hyphae and spores stock in soils, you have just to convert plowed and rotary power systems to no till cover cropping systems using leguminous plant diversities during the fallows periods like trifolium alexandrinum, persian clover, hairy vetch, viva fabae and others, seeded at high density levels. Mycorhization will develop progressively and naturally, year after year. You have to check during this conversion period if the soil is not compacted, if it is use a cracking soil that does not perturb the upper soil layer. Liming at the beginning is also necessary for the high development of earthorms. Avoid brassicacae if possible like mustard or radish as cover crop during fallow period. maize is necessary as mycotroph plant to initiate and develop mycorhiza. If you need I cand send you several research data that have been published on this topic.
thanks Paul Hepperly and Thierry Tetu for your valueable suggestions. i am working on "continuous cropping of EGGPLANT" using Garlic stalk and AMF alone and combine in pots..so you give me an idea about this
For continuous cropping that could help maximizing the soil quality your simple rotation may include garlic as the winter annual cycle and the use of eggplant as the second summer crop. For inoculum production of mycorrhizae grass maize and dry bean are planted in perlite vermiculite and 10% compost 10 % natural soil from a grass area in open field. When the frost comes the sorghum and bean. These plants will die off with frost and the growth media will be proliferated with a mixed mycorrhizal inoculum for both garlic and egglant production or other crops. The eggplant transplant can be planted in the inoculum mix and them planted in the garlic pots after their harvest. For vegetable production the use of a rotation from winter grain with interseeding and establishment of grass legume is optimum for preparing for successful vegetable production and improving the soil organic matter and providing for Nitrogen need. When soils are depleted 2 years of forage rotation is generally sufficient to revibe them. some ideas. PRH Use of growth mixtures with low Phosphorus content as vermiculite perlite is used to favor the mycorrhizae which do not proliferate at very high P contents. The soil is the source of local adapted mycorrhizae. The low content compost stimulates the plant development without over charging the P content.
thanks Paul..i am going to use garlic stalk and amf alone and their combination to overcome continuous cropping problems..i have already multiply AMF through maize..can you tell me how can we multiply amf in frost conditions under green house..
hi ghani muhammad and paul,
I did not understood what is the surface that you are concern for garlic ang eggplant;
of course like indicated Paul,if your surface is relatively small, you can through inoculation. Our experience concerns large ares, ie several hectares fields.
For us the problem is the cost of inoculation at this surface areas and if the soil is plowed, we did'not success with inoculations.
We have succeeded without inoculation by stopping the moalbord plow, using either direct seeding and /ou strip till.
See Agronomy 2016, 6, 38; In Winter Wheat, No-Till Increases Mycorrhizal Colonization thus Reducing the Need for Nitrogen Fertilization.
that's concern also maize, bean and canned peas (not allready sugarbeet).
we succeded also with mycorhiza using living mulch of clover with seed implantation with strip-till (maize and wheat).
