Specialty: Soil, water, and nutrient management
Soil sustainability, Water conservation and Nutrient management are the cornerstone of Sustainable Agriculture. My research program focuses on promoting sustainable agricultural practices in and around the Everglades Agricultural Area (EAA). One of the major concerns in the EAA is soil loss due to oxidation, locally referred to as “soil subsidence”. My goal is to identify agricultural options such as crop rotation and biochar that can add years to the productive life of a farmland. Farming practices have long been mindful of nutrient management as it relates to sufficiency and efficiency of nutrient utilization. My research program also explores the use of locally derived organic feedstocks and aquatic vegetation as an alternative source of slow release fertilizer when applied on depleted soils.
- Using submerged aquatic vegetation as biofilters to reduce phosphorus loading
A promising innovative treatment technology that has not yet been evaluated within the EAA is the approach that utilizes aquatic vegetation in conjunction with the calcium saturated surface waters to remove P from the water column. This will be achieved by circulating high P concentration farm canal water through the ditches prior to being discharged off site. Optimizing the flow through the ditches will allow the submerged aquatic vegetation (SAV) to uptake P. The vegetation will ultimately be harvested and incorporated back on to the fields. The removal of nutrients like phosphorus (P), nitrogen (N) and carbon (C) is accomplished by plant uptake. In addition to P-uptake by plants, adsorption to (or co-precipitation with) calcium carbonate could also result in the water column. As part of this demonstration study, submerged aquatic plants like Chara and Southern naiad will be introduced in farm ditches, and the flow of water through the ditches will be controlled using solar-powered, battery operated pumps. Chara is a genus of blue-green algae in the family Characeae. They are found in fresh water, particularly in limestone areas, where they grow submerged, attached to the muddy bottom. They are native to Florida and are most suited to shallow, hard water, typical of farm canal waters in the EAA.
The goal of this project is to demonstrate that EAA on-farm nutrient load reduction can be achieved through the use of solar-powered water pumps that circulate farm canal water through SAV-seeded field ditches at optimum flows that provide sufficient residence time for nutrient removal. In addition to uptake by aquatic vegetation, P removal from farm canal waters will occur via P co-precipitation with calcium carbonate. The presence of limestone caprock beneath the EAA fields and canals provides calcium saturated surface waters that can co-precipitate P from the water column with calcium carbonate during photosynthesis-induced pH elevations. We also anticipate a drop in dissolved organic carbon (DOC) concentration as part of the treatment demonstration. This is due to the fact that the SAV will fix a portion of the DOC as it establishes its growth; in addition to high photolytic activity associated with shallow ditch water.
- Environmental and cultural benefits of growing flooded rice
During the summer months, more than 50,000 acres of fallow sugarcane land is available for rice production. In 2015, nearly 23,000 acres of rice were planted in the EAA, yielding approximately one million hundred weights (cwt) of harvested green rice. The net value of growing rice as a rotation crop exceeds its monetary return. Production of flooded rice in the EAA provides several benefits to the agroecosystem. Growers greatly reduce soil subsidence, nutrient depletion, and insect pests by flooding fields. Production inputs like silicon, used to boost rice yields, has a carryover benefit on the subsequent sugarcane crop. One of the major concerns in the EAA is soil loss dues to oxidation, locally referred to as “soil subsidence.” Soil subsidence is the loss of top soils due to decomposition (mineralization) of organic matter. In the presence of oxygen (air) microbial activity facilitates organic matter mineralization.
Typically, deep water table and high temperatures tend to aerate the top soil, which in turn accelerates mineralization. Growing flooded rice provides anaerobic conditions that effectively stop subsidence of muck soils in the EAA during the hot summer months, effectively adding years to the productive life of the farmland. Since rice is grown during the wet season under flooded conditions, it helps to conserve water. Rice uses less water to produce a crop than sugarcane, citrus, pasture, or even the native sawgrass, and in most months its evapotranspiration requirement is less than all other crops grown in the area. Rice also has the potential to alleviate short-term nutrient loading within the EAA because the cultural practice to grow in the region does not include any nitrogen (N), phosphorus (P) or potassium (K) fertilization. Furthermore, rice can accumulate nutrients during the summer season and immobilize the nutrients when the potential for runoff of nutrient-rich water is the greatest. At the time of harvest only the grain portion of the rice plant is removed from the field. Rice straw and roots are incorporated into the soil after harvest. As the roots and straw decay, it releases nutrients that become available for uptake by the succeeding crop.
- Organic amendments and biochar in advancing sustainable agriculture
In parts of the EAA where soils are sandy, the application of using locally derived organic amendments and biochar as potential organic fertilizer has gained interest over the past few years. The use of local agricultural and urban organic residues as amendments in sandy soils of South Florida provide options to enhance soil properties and improve crop yields, while reducing waste and improving the environment. Products like bagasse, rice-hulls, horse bedding, palm fronds and yard waste are being evaluated for their agronomic traits to be used as soil amendments.
Producing biochar is a 2,000 year-old practice that converts organic waste into a soil enhancer that can retain carbon and nutrients, and increase soil biodiversity. Biochar can be an important tool to increase food security and cropland diversity in areas with severely depleted soils, scarce organic resources, and inadequate water and chemical fertilizer supplies. Current research initiatives involve testing the feasibility of using biochar produced from locally available feedstocks as possible soil amendment to grow vegetables. As part of this venture, our objective is to identify sources of feedstock, successfully convert it to biochar, characterize its properties, and test its effects on soil health and crop yields by conducting field-trials with local cooperating growers.
Application of biochar derived from agricultural byproducts such as rice-hulls, pine wood, and cotton seed meal to improve soil health and crop yields has tremendous promise. However, research-based information is lacking for applications of biochar in vegetable production systems. In addition to providing organic matter and nutrients to soils, biochar is more stable and resistant to microbial decay. Its application has shown to improve utilization of existing nutrients found in the soil or when applied with fertilization. Biochar treated soils have the potential not only to increase the water holding capacity, but also to retain water in soils longer. The surface areas of biochars are generally higher than sand and similar to that of clay, resulting in a higher cation exchange capacity, which is the ability of soils to retain vital nutrients for plant uptake. All of these qualities are extremely important for improving the quality of depleted soils. The goal of this venture is to develop working relationships amongst soil scientists, horticulturists, and local growers that will enhance our understanding of biochar and its role in sustainable agriculture.
- Discovering agronomic traits of aquatic vegetation
The presence of invasive aquatic vegetation in farm canals can impede drainage and irrigation and is cause for environmental concerns if not controlled properly. In the Everglades Agricultural Area (EAA) of south Florida, some of the common varieties of aquatic plants are water lettuce (Pistia stratiotes), filamentous cyanobacteria (Lyngbya wollei), southern naiad (Najas guadalupensis), torpedograss (family Poaceae), and Chara. While several management approaches including chemical control and mechanical harvesting have been attempted, they may not be cost effective options for growers. However, if aquatic vegetation can be utilized as a soil amendment or as a pesticide (fungicide, insecticide, herbicide) it has the added advantage of offsetting some of the cost associated with mechanical harvesting, resulting in cleaner canals. However, there are concerns that have typically hampered the large-scale utilization projects for invasive aquatic vegetation. These are (i) the high upfront capital costs and complexity of utilization programs relative to operational cost associated with a control program; (ii) the “perceived” low value of products from aquatic plants relative to the expense of handling feedstock that is composed of almost 90% water; (iii) the possibility that any demonstration of value for invasive aquatic vegetation could have the perverse effect of speeding. While all these factors remain as important considerations, ongoing research into the beneficial uses of aquatic vegetation has the potential to reevaluate the current control strategies for many water bodies. Lab and greenhouse-scale trials are being conducted to evaluate the allelopathic effects of these aquatic plants on the agronomic industry.
