Data derived from annual USDA-NASS Crop Production ReportsEvery farmer's dream is to have a field that contains fertile soil, sufficient nutrient content, and a right balance between beneficial and harmful microorganisms and insects... Spatial variability refers to the difference in the yield of certain areas in the same field due to unequal characteristics of soil, plants, and terrain. Factors affecting corn yield variability:Soil textureThe percentage of sand, gravel, and clay in the soil determines its texture. With the help of a simple manual technique, one can quickly identify the soil texture in a specific field. Different texture in spatial distribution differently affects corn yield through variations in nutrient capacity and availability, water capacity and transport, binding or decomposition of pesticides, as well as soil stability itself to different destructive forces...

In the 52 Weeks of Agronomy Series I've been posting on my website, I took a week and explained this agronomist's take on soil health vs. soil fertility. To read the article and get caught up on the rest of the series follow along at News | The Accidental Agronomist I spoke at a conference in front of 200 farmers and used the term, custom soil fertility programs. At the time I was working as a sales agronomist for a fertilizer company that offered custom fertilizer recommendations based on a farmer’s soil tests...

FARM WALKS WITH THE SOIL FARMERS OF THE YEAR 2018The winners of the FCCT Soil Farmer of the Year competition opened their gates over four days and provided a veritable masterclass in managing soils. Spanning a range of soil types, management systems and enterprises, attending farmers gained insights into their award winning management and a better understanding as to why these farms had been picked as the top three in this year’s competition. The Soil Farmer of the Year Competition, now in its third year, is run by the Farm Carbon Cutting Toolkit and Innovation for Agriculture. The competition aims to find farmers and growers who are engaged with, and passionate about managing their soils in a way which supports productive agriculture, reduces greenhouse gas emissions and builds soil health, organic matter and ultimately, carbon... Simon has been working on improving his soils for the last 20 years, and moved to a notill system 12 years ago, being flexible with both management and rotations to prioritise soil health...

, now is a good time to prepare for your soil sampling program. Most universities and the NRCS recommend taking soil samples in the off-season, after the last crop harvest, and before the next cash crop is planted... But before you can grab your soil probe and head out to the field, you need to understand best soil sampling practices and have a plan of action for collecting your samples, so you can accurately capture the soil chemistry and variability of your fields. Poor soil sampling practices can result in incorrect data, which can end up costing you in either inputs or yield. “The foundation of understanding or making an appropriate recommendation comes from having a representative soil sample,” says Jason Ackerson, a Purdue University soil scientist...

First of all,let us understand the soil structureThe soil is a porous system... The solid material in the soil includes both mineral and organic matter. The liquid part refers to the moisture of the soil,which is preserved and moved between the pores of the soil and is the most active part of the soil. The gas part refers to the air of the soil and it is filled with pores that are not occupied by moisture... Crumb structure is a type of soil structure in which the structural units or peds have a spheroidal or crumb shape...

What’s Soil SalinizationSoil salinization is one of the most vital soil problems for agricultural production... Soil salinization usually occurs in arid areas, In these areas, soluble salt ions accumulate in the soil. In these areas where plant growth requires irrigation, the Evaporation and transpiration process leaves salt in the soil. In the beginning, the salt will reduce soil productivity and limit crop yields. As the salt content increases, it kills the vegetation and soil microorganism...

Soilless cultivation is an innovative process that was introduced in recent years for protected crops. This practice has been established for the large-scale production of fresh vegetables and ornamental plants, especially in the countries of Northern Europe, with the main purposes of:- Increasing production- Optimizing acreage - Reducing working times- Reducing the need for water and fertilizers - Optimizing climatic conditionsThe continuous climate changes, the increasing interest in environmental impacts, and the availability of cheap facilities and simple technologies all lead to an increased use of soilless cultivation in commercial applications. When talking about soilless crops, we’re referring to two types of systems:- Real hydroponics, without substrate: the root system of a plant is directly in contact with the water and the nutrient solution (floating system, nutrient film technique, aeroponics)- Hydroponics with substrate: the plant grows on inert, organic materials, or a mixture between them (cultivation bags, slabs, pots or bins)In these systems, fertigation feeds the plants and involves the use of water-soluble fertilizers... Advantages and disadvantages of soilless cultivationSoilless cultivation has numerous advantages like:- Increasing unit yields and anticipating harvest- Improving the quality of the final product, such as the size and uniform physical-chemical characteristics of the fruits, due to the controlled and accurate management of nutrition and climatic parameters- Using easily replaceable structures in case of reconversion- Reducing the labor for demanding processing operations, such as tillage and soil disinfection- Reducing water consumption, especially in plants managed in a closed cycle in areas with limited water availability- Reducing the use of pesticides and adopting integrated pest management strategies more easilyAlthough the advantages can be very encouraging in the decision to adopt these systems, it is also necessary to consider the disadvantages and difficulties that must be faced: - Insufficient know-how to understand how to manage fertigation, irrigation, crop care and automatic control unit technology - Need for constant monitoring of various parameters, such as EC, pH, nutrient solution recipe and climate- Greater risk of incurring water or saline stress in case of a blackout, which renders the whole system unusable - Medium-high initial investments - Difficulty in reaching potential productions in the first years, due to facilities management problems - Difficulty in disposing of inorganic substrates at the end of use - Dispersion of the exhausted nutrient solution in the surface layers when using open-cycle systemsWhen you decide to cultivate with a soilless system, you need to choose the ideal system type depending on the place where you intend to work, the plant species, the size, and the budget available... 4: Soilless system with pots for grape cultivation...

While it only makes up a small percentage of most soils, the Sustainable Agriculture Research & Education (SARE) says it’s the “very foundation for healthy and productive soils” — and the more organic matter there is, the better the results. Consider the following findings from SARE and the NRCS:A study of soils in Michigan demonstrated potential crop-yield increases of about 12% for every 1% organic matter...

You can pick the right seed, use the right equipment, apply the right inputs, and plant at the right depth, but without the right soil temperature, your crops are likely to struggle... Why Soil Temperature MattersWhile soil temperature has an impact on the soil and crop production throughout the growing season, the NRCS says it’s most critical at planting, when it drives seed germination and directly affects plant growth. “Most soil organisms function best at an optimum soil temperature,” says the USDA agency, adding that soil temperature influences soil moisture content, aeration, and the availability of plant nutrients. This graphic from the NRCS shows what happens to plants and soil life based on the soil temperature. The soil has to warm up to a certain degree for plants to get off to a good start, but if it continues to heat up and does so rapidly, that can harm plant growth...
