Mineral nutrition of vegetable crops: XXV - Mineral nutrition of new zealand spinach plant (Tetragonia expansa Murr.)

The present work was carried out in order to study: a - the effect of omission and presence of the macronutrients and boron on the growth of the plants; b - deficiency symptoms of macronutrients, as well of boron; c - the effect of the deficiency of each nutrient on the chemical composition of the plants. Young spinach plants were grown in pots containing pure quartz sand. Several times a day the plants were irrigated by percolation with nutrient solutions. The treatments were: complete solution and deficient solution, in which each one of the macronutrients was omitted as well boron. Soon as the malnutrition symptoms appered, the plants were harvested and analysed chemically. - symptoms of malnutrition are easily observed for N, K, Ca and B. - symptoms of malnutrition for P, S and Mg are not easily identified. - the nutrient content, in dry matter, in deficient leaves and healthy leaves is:O trabalho teve como objetivo estudar alguns aspectos da nutrição mineral do espinafre (Tetragonia expansa Murr.) no que concerne: 1 - Efeitos da omissão dos macronutrientes e do boro, na obtenção de um quadro sintomatológico; 2 - Efeitos das carências na produção de matéria seca e composição química da planta. Mudas com trinta dias de idade foram transplantadas para soluções nutritivas carentes nos macronutrientes e/ou em boro. A coleta das plantas foi realizada quando os sintomas de deficiência se tornaram evidentes. No material seco procedeu-se a análise química. Os dados mostram que: 1 - os sintomas visuais de deficiência de N, K, Ca e B apresentam-se bem definidos; sendo que os de P, Mg e S são de difícil caracterização ; 2 - os teores dos nutrientes em plantas sadias e deficientes são

Some Problems of Mathematical CAL

This paper describes briefly some problems of mathematical CAL and suggests ways to combat them. Within the context of the CALM Project for Computer Aided Learning in Mathematics we highlight three main areas of difficulty—mathematical display, input and evaluation. These problems are illustrated using examples from software developed at the Heriot-Watt University in Edinburgh and at Southampton University; the examples are taken from both calculus and algebra

The Calm before the storm! CAL in University Mathematics

A Computer Aided Learning project in Mathematics (the CALM Project) is based at the Heriot-Watt University in Edinburgh. It is one of the projects currently in receipt of funding from the Computer Board of the United Kingdom as part of the Computers in Teaching Initiative in British Universities.The CALM Project seeks to produce computer enhanced teaching packages which will back-up the conventional teaching of Calculus to large groups of first year engineering undergraduates at a typical Scottish University. The project has been underway for just over one year and some of the software prepared by the CALM team has been tested by one section of the class. During this testing period we have embarked on a formative evaluation of the software and of its impact on student learning practices.In this article the writers present an outline of the evaluation procedure. In addition, details are given of the software tools used to produce the CALM programs
