Estimating Phosphorus loss in runoff from manure and fertilizer for a Phosphorus loss quantification tool
Nonpoint-source pollution of fresh waters by P is a concern because it contributes to accelerated eutrophication. Given the state of the science concerning agricultural P transport, a simple tool to quantify annual, field-scale P loss is a realistic goal. We developed new methods to predict annual dissolved P loss in runoff from surface-applied manures and fertilizers and validated the methods ...

Nitrogen recovery from source-separated human urine using clinoptilolite and preliminary results of its use as fertilizer
The use of source separated human urine as fertilizer is one of the major suggestions of the new sanitation concept ECOSAN. Urine is rich in nitrogen, phosphorus and potassium which act as plant nutrients, however its salinity is high for agricultural and landscape purposes. Moreover, characteristics change significantly throughout storage where salinity increases to higher values as the ...

Pond fertilization / Aquaculture
Just as fish need good water quality conditions to thrive, they also need an abundant supply of food to grow. We can provide food for our fish in two different ways: We can give them “artificial” feeds that are prepared either commercially or at home, or we can ensure that they have an abundance of natural foods by using fertilizers to increase pond productivity. In either case, it is ...

Agrochemicals in field margins—assessing the impacts of herbicides, insecticides, and fertilizer on the common buttercup (Ranunculus acris)
The effects of herbicide, insecticide, and fertilizer inputs on the common buttercup Ranunculus acris in field margins were studied in an experimental field study. The test design allowed us to investigate the single and combined effects of repeated herbicide, insecticide, and fertilizer applications in successive growing seasons. To assess the effects of the agrochemical applications on R. ...

Population growth data is bad news for the climate
The demographers may have got it wrong. New projections say the population of the planet will not stabilise at 9 billion sometime this century. In fact, there is an 80% likelihood that, by 2100, it will reach at least 9.6 bn − and maybe rise as high as 12.3 bn. The latest data, published in the US journal Science, has profound and alarming implications for political stability, food ...

Leaf Cares Article - Foliar Analysis
What is Leaf tissue testing? Leaf tissue testing is a crucial process for evaluating the concentration of essential elements within plant tissue. Essential nutrients, categorised as micronutrients and macronutrients, play key roles in sustaining the plant’s life cycle. Micronutrients, required in smaller amounts and macronutrients needed in larger amounts are essential for achieving ...

Fertility status, trace elements and heavy metal pollution of agricultural land irrigated from the Gediz River
The effect of the Gediz River, polluted by industrial and domestic wastes, on fertility status and trace elements and heavy metal pollution of agricultural land irrigated from this river was investigated. For this purpose, soil samples were collected in August 1998 between the source of the Gediz River (Murat Mountain) and its mouth (Aegean Sea). Soil samples were collected from 12 different ...

100% geese reduction after placing the Agrilaser Autonomic in the farm in Achthuizen and Oude-Tonge - Case Study
Thousands upon thousands of geese were terrorizing the fields of NIVU at Goeree-Overflakkee. The Installation of two Agrilaser Autonomic lasers means an end to the plague. The Agrilaser Autonomic at farmer NIVU Situation before Farmer NIVU in Achthuizen and Oude-Tonge owns over 400 hectares of agricultural land adjacent to water. Therefore, thousands of geese are a daily threat to both the ...

Efficiency concept under stochastic consideration of water value in irrigated agricultural land in Crete, Greece
Water is an increasingly scarce and valuable resource. It is generally accepted that there is a finite supply of water. As economies grow there is an increasing demand for water. The application of water to agricultural lands for irrigation is one of the essential uses of this natural resource in many areas. There is competition among agriculture, industry, and human consumption for the ...

Evaluating cumulative effects of anthropogenic inputs in Prince Edward Island estuaries using the mummichog (Fundulus heteroclitus)
Estuarine eutrophication as a result of agricultural land use including the use of chemical fertilizers is increasing worldwide. Prince Edward Island, Canada has very high agricultural intensity by international standards with approximately 44% of the land area under production, and some watersheds in excess of 75% agricultural land‐use. The type of agriculture is also intensive with primarily ...

The manage database: nutrient load and site characteristic updates and runoff concentration data
The 'Measured Annual Nutrient loads from AGricultural Environments' (MANAGE) database was developed to be a readily accessible, easily queried database of site characteristic and field-scale nutrient export data. The original version of MANAGE, which drew heavily from an early 1980s compilation of nutrient export data, created an electronic database with nutrient load data and corresponding site ...

Soil Sensor-driven Precision Agriculture
For centuries, farmers have relied on intuition, experience, and a hint of superstition to nurture their crops. While time-honored technologies still have value, the modern agricultural landscape has a powerful ally: precision agriculture. At the heart of this revolution is a silent orchestra of information-gathering heroes: soil sensor. Whispering wisdom from the earth: Gone are the days of ...

Can pulse crops play a role in mitigating greenhouse gases from North American agriculture?
The atmospheric buildup of greenhouse gases (GHGs) is a serious environmental issue. Globally, agricultural activities are an important source of anthropogenic GHGs, contributing 20% of the annual atmospheric increase. Management choices largely determine if agricultural soils will be a source, a sink, or will be neutral with respect to GHG net flux. The proportion of agricultural land that is ...

Is organic farming climate friendly?
Think organic farming is climate friendly? You might want to think again. A study published recently in the journal Agriculture and Human Values suggests that as organic agriculture emulates conventional industrial agriculture, the environmental benefits may not be the slam-dunk that Earth-loving proponents might like them to be. It’s well known that organic practices offer climate ...

Critical source area management of agricultural phosphorus: experiences, challenges and opportunities
The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

Soil Microbial Community Response to Land Use Change in an Agricultural Landscape of Western Kenya
Tropical agroecosystems are subject to degradation processes such as losses in soil carbon, nutrient depletion, and reduced water holding capacity that occur rapidly resulting in a reduction in soil fertility that can be difficult to reverse. In this research, a polyphasic methodology has been used to investigate changes in microbial community structure and function in a series of tropical soils ...

Revolutionizing Agriculture with Intelligent Soil Sensors
Unlocking Data-Driven Insights for Sustainable and Efficient Farming For centuries, agriculture has relied on tradition and intuition, with farmers often relying on their experience and gut feeling to make decisions about their land. However, the 21st century has ushered in a new era in agriculture, one driven by data and innovation. At the forefront of this revolution are intelligent soil ...

Losing Soil
In 1938, Walter Lowdermilk, a senior official in the Soil Conservation Service of the U.S. Department of Agriculture, traveled abroad to look at lands that had been cultivated for thousands of years, seeking to learn how these older civilizations had coped with soil erosion. He found that some had managed their land well, maintaining its fertility over long stretches of history, and were ...
